what's the differences between GoldVIP's ATF and bsp32's ATF

nevc — Mon, 04 Jul 2022 06:36:52 GMT

1. follow the GoldVIP 1.1.0 User Manual, Deploy GoldVIP SD-card image, Deploy images to Flash, configure the DIP switches for NOR Flash Boot mode (set SW4.7 to OFF) and then power on the board, all run well.

2. follow the S32G2_LinuxBSP32.0_User_Manual, manually build the uboot get arm-trusted-firmware
fip.s32.

cd arm-trusted-firmware
make CROSS_COMPILE=/path/to/your/toolchain/dir/bin/aarch64-none-linux-gnu- \
ARCH=aarch64 PLAT=<plat> BL33=<path-to-u-boot-s32.bin>

3. Deploy manually build fip.s32 to the sdcard.

sudo dd if=<path/to/fip.s32> of=/dev/<sdcard_dev> skip=512 seek=512 \
iflag=skip_bytes oflag=seek_bytes conv=fsync,notrunc

4. Insert SD card on RGB2 board,power on. There is an error.

My question is: is there any differences between GoldVIP's ATF and bsp32's ATF.

How can I get the GoldVIP's ATF (uboot).

Hi,

There are a few differences: (GoldVIP ATF has a different alignment plus the u-boot variables are added). See this patch: https://source.codeaurora.org/external/autobsps32/goldvip/meta-gvip/tree/recipes-bsp/arm-trusted-firmware/files/0001-align-fip-to-64B.patch?h=develop

However, it doesn't really make sense to re-compile the ATF for GoldVIP, as it's already present in the RAW SD Card partition and in the FAT32 partition of the SD card.

See here (fip.s32-sdcard).

Hello nevc,

You need check with your FAE, according to your BSP is the BSP32, but normal BSP don't include the ATF, So you need to check with your FAE.

Thank you very much, it really works.

I followed you instruction, updated the arm-trusted-firmware and u-boot as the patches said.

But when I power on the board, booted from SD card mode, the serial port has no output. Why ?

I want to port GoldVIP on our designed board, there are some changes have to be made in u-boot, So I need to know how to get the original GoldVIP ATF.

Please help me, thanks a million.

Hi, nevc,

U-boot needs to be aware that it's booting XEN. This is missing from your U-boot (contained in ATF) configuration.

Here's how you can enable it: https://source.codeaurora.org/external/autobsps32/meta-alb/tree/recipes-bsp/u-boot/u-boot-s32/build/xen_config.cfg?h=release/bsp32.0-3.2

In order to streamline the process, I would advise you to use the yocto environment from meta-gvip.

Hi,

Thanks again for your reply.

I added the CONFIG_XEN_SUPPORT=y on file s32g274ardb2_defconfig; then rebuild uboot and AFT.

Set the board booted from Nor Flash mode, the log is same:

Set the board booted from SD card mode, the serial port has no output.This is really confusing to me.

I'm not familiar with yocto, I'll try to use yocto to build the project.

Thanks again.

Hi,

Did you also update the flash region where ATF resides?

Hi,

1. Update my build fip.s32 on SD card FAT32 partition /boot_s32g27; rename it to fip.s32-sdcard

2. Set the board booted from Nor Flash, stop in u-boot console when prompted, and run the command: run write_atf

3. Repower on the board:

Hi,

Let me explain a bit the boot process for GoldVIP (A53-ATF related process).

1. The M7 bootloader boots BL2 from ATF (first bootloader) from QSPI.

2. BL2 boots BL31, BL32 (if applicable), BL33 (u-boot) from SD.

You need to have the same FIP image both in SD card and in the QSPI flash. I understand this seems redundant, but otherwise, we couldn't accommodate standalone SD and QSPI-based boot.

Try to keep in sync the FIP image on the QSPI with the one on the SD card. It should work.

Hi，

I've deployed my build FIP image to QSPI Flash and SD card, the same FIP image. But it doesn't work.

I'd like to write down how to get my manually build FIP image:

1. Get uboot and ATF source code from git.

2. Update uboot patches as this link said:files\u-boot\recipes-bsp - goldvip/meta-gvip - NXP S32G Vehicle Integration Platform (GoldVIP) Yocto Layer (codeaurora.org)

Update s32g274ardb2_defconfig file with CONFIG_XEN_SUPPORT=y

then manually build, get the u-boot-s32.bin file.

3. Update ATF patch as this link said: files\arm-trusted-firmware\recipes-bsp - goldvip/meta-gvip - NXP S32G Vehicle Integration Platform (GoldVIP) Yocto Layer (codeaurora.org)

then use this command to get fip.s32 file:

cd arm-trusted-firmware
make CROSS_COMPILE=/path/to/your/toolchain/dir/bin/aarch64-none-linux-gnu- \
ARCH=aarch64 PLAT=<plat> BL33=<path-to-u-boot-s32.bin>

4. Deploy manually build fip.s32 to SD card and QSPI Flash.

5. Set the board boot from QSPI Flash, the log is as the picture show.

6. Set the board boot from SD card, no output from the serial port.

There must be something else I have to do to get the same fip.s32-sdcard as the GoldVIP.

When use the GoldVIP's fip.s32-sdcard file, no matter boot from QSPI or SD card, all work well.

Hi, Nevc,

Can you please confirm that you have the same file in the SD RAW partition and QSPI?
The GoldVIP image does this setting by default, so I'm mostly worried about this setting.

Hi, nxf45013,

I'm really appreciate your reply, it means a lot to me.

I'm pretty much sure that the SD RAW partition and QSPI Flash have the same file.

Deploy fip.s32 to SD card, use following command:

sudo dd if=<path/to/fip.s32> of=/dev/<sdcard_dev> skip=512 seek=512 \
iflag=skip_bytes oflag=seek_bytes conv=fsync,notrunc

Deploy fip.s32 to QSPI flash as following:

boot from QSPI flash, stop in u-boot console when prompted, run write_atf
(Of course I've updated my build fip.s32 to SD card boot partition)

I've uploaded my build fip.s32 file as an attachment, may you use it on your board to test if it works.

Thanks a million, i really mean it.

Hi,

The format of the file looks fine. It seems that BL2 and BL31 run fine. Could you please also share the contents of boot_info.c?

Also, is u-boot set to boot from SD card?

Vlad

Hi,

"Also, is u-boot set to boot from SD card? "

Do you mean where does bootloader get the u-boot? from SD card or QSPI Flash ?

I didn't change anything about bootloader, so bootloader get ATF(u-boot) form QSPI Flash at address 0x00100000.
