General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas. For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products.
1. Precaution against Electrostatic Discharge (ESD) A strong electrical field, when exposed to a CMOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop the generation of static electricity as much as possible, and quickly dissipate it when it occurs. Environmental control must be adequate. When it is dry, a humidifier should be used. This is recommended to avoid using insulators that can easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices. 2. Processing at power-on The state of the product is undefined at the time when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of register settings and pins are undefined at the time when power is supplied. In a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the time when power is supplied until the reset process is completed. In a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the time when power is supplied until the power reaches the level at which resetting is specified. 3. Input of signal during power-off state Do not input signals or an I/O pull-up power supply while the device is powered off. The current injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal elements. Follow the guideline for input signal during power-off state as described in your product documentation. 4. Handling of unused pins Handle unused pins in accordance with the directions given under handling of unused pins in the manual. The input pins of CMOS products are generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of the LSI, an associated shoot-through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal become possible. 5. Clock signals After applying a reset, only release the reset line after the operating clock signal becomes stable. When switching the clock signal during program execution, wait until the target clock signal is stabilized. When the clock signal is generated with an external resonator or from an external oscillator during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Additionally, when switching to a clock signal produced with an external resonator or by an external oscillator while program execution is in progress, wait until the target clock signal is stable. 6. Voltage application waveform at input pin
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between VIL (Max.)
and VIH (Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the input level
is fixed, and also in the transition period when the input level passes through the area between VIL (Max.) and VIH (Min.). 7. Prohibition of access to reserved addresses Access to reserved addresses is prohibited. The reserved addresses are provided for possible future expansion of functions. Do not access these addresses as the correct operation of the LSI is not guaranteed. 8. Differences between products Before changing from one product to another, for example to a product with a different part number, confirm that the change will not lead to problems. The characteristics of a microprocessing unit or microcontroller unit products in the same group but having a different part number might differ in terms of internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, such as characteristic values, operating margins, immunity to noise, and amount of radiated noise. When changing to a product with a different part number, implement a system- evaluation test for the given product.

Linux Interface Specification Yocto recipe Start-Up Guide 5. Exporting Toolchains
Please refer Documents from Yocto Project to export Toolchains such as http://www.yoctoproject.org/docs/current/adt-manual/adt-manual.html. And please use build target of bitbake as “core-image-weston(qt)-sdk -c populate_sdk” to generate package.
Note) When you use “ld” directly but not via gcc (in case of building Kernel, Driver or U-Boot), please disable LDFLAGS with ‘unset LDFLAGS’. Furthermore, in kernel build, ‘make menuconfig’ occurs error by ncurses. In this case, please set PKG_CONFIG_PATH and disable PKG_CONFIG_SYSROOT_DIR.
$ export PKG_CONFIG_PATH=$OECORE_NATIVE_SYSROOT/usr/lib/pkgconfig $ unset PKG_CONFIG_SYSROOT_DIR
Note) Please do not use same shell environment to other compilation/debugging purpose (also make menuconfig of linux kernel, e.g.) but cross compilation for RZ/G2E|G2M|G2N|G2H which shell environment with “source” command to setup environment variables for the SDK. Because some environment variables for cross compilation interferes execution of other tools on the same shell environment.
Example of instruction:
In following examples, it’s assumed that it’s already extracted and prepared recipe environment such as in the instructions of Section 3 (must done just before execution of bitbake, at least). You may reuse ${WORK}/build while you reuse same configuration after executing bitbake as in Section 3 for this purpose.
Step 1 configure architectures of Host PC which are installed this toolchain
Please modify SDKMACHINE description on ${WORK}/build/conf/local.conf.
On ${WORK}/build/conf/local.conf
# This variable specified the architecture to build SDK/ADT items for and means # you can build the SDK packages for architectures other than the machine you are # running the build on (i.e. building i686 packages on an x86_64 host. # Supported values are i686 and x86_64 #SDKMACHINE ?= "i686" SDKMACHINE ?= "x86_64"
Note) 32bit Ubuntu is not supported. Ubuntu 16.04 and Ubuntu 18.04 can be used to build BSP and SDK, but when install SDK should use Ubuntu 18.04. (If install SDK to Ubuntu 16.04, an error will appear. If ignore that error, installed SDK can still be used to build user applications, but building kernel or kernel modules is not possible)
R01US0398EJ09 Rev.1.09 Page 17 of 32 Aug. 31, 2021
Linux Interface Specification Yocto recipe Start-Up Guide
Step 2 building toolchain package with bitbake
$ cd ${WORK}/build $ bitbake core-image-weston(qt)-sdk -c populate_sdk $ cp tmp/deploy/sdk/poky-glibc-x86_64-core-image-weston(qt)-sdk- aarch64-toolchain-2.4.3.sh (shared dir. where able to access from each Host PCs)
Note) Please perform “bitbake core-image-minimal -c populate_sdk” in BSP Only.
Step 3 Install toolchain on each Host PCs
$ sudo (shared dir. where able to access from each Host PCs)/poky-glibc- x86_64-core-image-weston(qt)-sdk-aarch64-toolchain-2.4.3.sh
[sudo] password for (INSTALL person): (password of your account) Enter target directory for SDK (default: /opt/poky/2.4.3): (just a return) Extracting SDK...done Setting it up...done
When it request to re configure please just enter to keep default value
Compile also drivers which will not load (COMPILE_TEST) [N/y/?]
Step 4 setup environment variables for each compilation on each Host PCs
Please setup environment variables as follows or integrate set-up sequence into your build script or Makefile.
$ cd (Your working directory) $ source /opt/poky/2.4.3/environment-setup-aarch64-poky-linux $ export LDFLAGS=”” $ ${CC} (Your source code).c …..

Linux Interface Specification Yocto recipe Start-Up Guide 6. Memory map
Following from Figure 2 to Figure 6 show memory map of this RZ/G2E|G2M|G2N|G2H Linux BSP package.
Note)
- The volume of SDRAM is total 2GB (RZ/G2E System Evaluation Board EK874), 4GB (RZ/G2M System Evaluation Board HiHope-RZG2M), 4GB (RZ/G2N System Evaluation Board HiHope-RZG2N), 4GB (RZ/G2H System Evaluation Board HiHope-RZG2H).
- 2GB from 0x00_4000_0000 to 0x00_BFFF_FFFF is a shadow area from 0x04_0000_0000 to 0x04_7FFF_FFFF.
- The following regions are used as a secure region. It doesn’t allow U-Boot and kernel to access those regions.
➢ 63MB from 0x00_43F0_0000 to 0x00_47DF_FFFF in SDRAM
➢ 16KB from 0x00_E630_0000 to 0x00_E630_3FFF in System RAM
- In case the configuration of BSP + 3D Graphics + Multimedia package, it doesn't allow to store any data in "CMA for Lossy comp" (default: 0x00_5400_0000 - 0x00_56FF_FFFF) region which is for media playback before kernel boots up. Any data stored in this region are read through the decompression module in AXI- Bus, so a normal data (not a decoded frame) will be corrupted.

➢ 2GB from 0x04_8000_0000 to 0x04_EFFF_FFFF
Kernel region consists of 2 part: (RZ/G2H System Evaluation Board HiHope-RZG2H)
➢ 1920MB from 0x00_4800_0000 to 0x00_BFFF_FFFF
➢ 2GB from 0x05_0000_0000 to 0x05_7FFF_FFFF
There are three types of CMA regions.
They are defined in device tree (arch/arm64/boot/dts/renesas/xxxx.dts).
➢ Default CMA region: It is for kernel, general drivers and multimedia package.
linux,cma { compatible = "shared-dma-pool"; reusable; reg = <0x00000000 0xXXXXXXXX 0x0 0xYYYYYYYY>; linux,cma-default; };
0xXXXXXXXX is start address of CMA region. 0xYYYYYYYY is size of CMA region. Note)
⚫ 128 MB in this CMA (RZ/G2M (v1.3, v3.0) |G2N|G2H 512MB, RZ/G2E 256MB) is reserved for kernel and general drivers, and the remaining RZ/G2M (v1.3, v3.0) |G2N|G2H 384 MB, RZ/G2E 128MB is reserved for multimedia package. ⚫ The CMA region can be adjusted by changing the start address and the size.
⚫ Should take care of the lack of memory allocated by kernel and general drivers when reducing the region size.

➢ CMA region for MMP: It is for multimedia package (specific H/Ws).
mmp_reserved: linux,multimedia { compatible = "shared-dma-pool"; reusable; reg = <0x00000000 0xXXXXXXXX 0x0 0xYYYYYYYY>; };
0xXXXXXXXX is start address of CMA region. 0xYYYYYYYY is size of CMA region. Note)
⚫ Refer to User’s manual of Memory Manager in order to change CMA region for MMP.

Linux Interface Specification Yocto recipe Start-Up Guide 8. System Service
In RZ/G2 VLP64 environment, some services are added to root filesystem to assist related drivers.
8.1 Watchdog Service
Watchdog Service is a systemd service, which is used to generate a reset when system is freeze.
It is automatically loaded in root filesystem and runs background during operation with binary file:
/usr/bin/watchdog-test -d -t 60 -e
This binary is compiled from “tools/testing/selftests/watchdog/watchdog-test.c” in kernel source code.
The meaning of each parameter:
• -d: Turn off the watchdog timer
• -t: set time out to 60s
• -e: Turn on the watchdog timer
• -p: set ping rate (default value is 1s if not set)
To control Watchdog Service interface, we can refer similar commands of systemd service on linux. The following table show supported commands:
Table 2 Supported commands
Command Description systemctl stop watchdog Stop Watchdog Service systemctl start watchdog Start Watchdog Service systemctl restart watchdog Restart Watchdog Service systemctl disable watchdog Disable Watchdog Service in root filesystem systemctl enable watchdog Enable Watchdog Service in root filesystem
Watchdog Service is automatically activated by default. To turn off Watchdog Service, please choose one of the following ways:
• Stop Watchdog Service in runtime (Turn off only once. If you reset or powering up board again, watchdog service still starts again):
o systemctl stop watchdog.
• Disable Watchdog Service in runtime (Turn off completely. If you reset or powering up board again, watchdog service does not start):
o systemctl stop watchdog.
o systemctl disable watchdog.
R01US0398EJ09 Rev.1.09 Page 31 of 32 Aug. 31, 2021
Linux Interface Specification Yocto recipe Start-Up Guide
• Remove Watchdog Service from BSP packages: remove “watchdog” package in “recipes-images/core-image- renesas-base.inc”
IMAGE_INSTALL_append = " \ bash \ v4l-utils \ i2c-tools \ coreutils \ - watchdog \ "
8.2 Video Input Initializing Service
In RZ/G2 environment, there is a service named “vin” which automatically sets connecting among VIN, CSI2 and OV5645 camera sensor. This script automatically sets default links for:
Processor CSI20 CSI40
RZ/G2H VIN4/VC0 VIN0/VC0
RZ/G2M v1.3 VIN4/VC0 -
RZ/G2M v3.0 VIN4/VC0 VIN0/VC0
RZ/G2N VIN4/VC0 VIN0/VC0
RZ/G2E - VIN4/VC0
To change the connection in runtime, user can use a script at “/home/root/vin-init.sh” created by vin service then modify some parameters which are described in this script based on user’s purpose and connection tables (Table 4.3, 4.4, 4.5, 4.6 in Video Capture User’s Manual).
To remove “vin” service from BSP packages, please remove “vin-init” package in “recipes-images/core-image-bsp.inc”:
IMAGE_INSTALL_append = " \ …. rt-tests \ ltp \ openssl \ - vin-init \ "
