still unable to boot from qspi-nand

[ASkri.1]

In addition to this question:

https://community.st.com/s/question/0D53W00000pUh4gSAC/tfa-and-uboot-custom-compile-fails

I'm still unable to boot from qspi. I addition to question about I've discovered, that it's necessary to add STM32MP_SPI_NAND=1 option to t-fa build command line

There are two issues:

1.If I add it to commend line as described in wiki I've got following compilation error while compiling TF-A for USB :

arm-ostl-linux-gnueabi-ld.bfd: BL2's RO content has exceeded its limit.

arm-ostl-linux-gnueabi-ld.bfd: section .data VMA [000000002fffa000,000000002fffa543] overlaps section ro VMA [000000002ffea000,000000002fffafff]

arm-ostl-linux-gnueabi-ld.bfd: region `ROM' overflowed by 5444 bytes

....

../Makefile.sdk:190: recipe for target 'tf-usb' failed

2.If I add it only for nand target all ok:

Makefile.sdk line 46:

# Init default config settings

TF_A_BINARY_nand ?= tf-a

TF_A_MAKE_TARGET_nand ?= all

And I've regenerated UBI image to get it fitted to 128Mb flash

Not I've got following console output while trying to boot qspi:

Could you please give me steps to debug this issue?

Hi @ASkri.1​ ,

I confirm that you can't build tf-a combining STM32MP_SPI_NAND=1 and STM32MP_RAW_NAND=1 or STM32MP_SPI_NAND=1 and STM32MP_USB_PROGRAMMER = 1

Those combination exceed the max authorized size.

But your trial with only STM32MP_SPI_NAND=1 trigged that this setup was not present in our delivery and maybe require some tuning.

I will ask some expert and come back

Hi, Olivier! I just want to point, that building with STM32MP_SPI_NAND=1 is not the main purpose... I just want to get qspi boot ok. According to TF-A src it is necessary to set this def. Thank you in advance Looking forward for your reply вт, 8 июн. 2021 г. в 14:55, ST Community :

Hi!

Do you have any news on this issue?

Thank you in advance

Looking forward for your reply

Hello,

ST does not deliver a ready to use configuration for the snand because we don't have any board reference to provide to the customers.

snand was a change request during the project but many customers are using it now. It is clear for us we need to improve all the documentation around this use case that is now tested on every delivery internally.

Some snand can be booted from Rom code but for TF-a, some parameters need to be provisioned from the OTP (this is the standard way of working) but in your case you may force the snand config of your memory directly in TF-A code.

I/ First of all, print the config Tf-a is seeing:

in drivers/mtd/nand/spi_nand.c:

VERBOSE("SPI_NAND Detected ID 0x%x 0x%x\n", id[0], id[1]);

VERBOSE("Page size %i, Block size %i, size %lli\n",

spinand_dev.nand_dev->page_size,

spinand_dev.nand_dev->block_size,

spinand_dev.nand_dev->size);

Replace VERBOSE by INFO to see the trace in the console.

II/ configure the snand:

In ./plat/st/stm32mp1/stm32mp1_boot_device.c:static int get_data_from_otp(struct nand_device *nand_dev, bool is_slc)

you will see the different parameters TF-a needs from the OTP.

You can patch on a first step the values from your snand memory:

nand_dev->page_size

nand_dev->block_size

nand_dev->nb_planes

I think this is the issue here but if still not working, please give your snand reference.

Hi, Bernard! Thank you very much for your help - there is big step ahead, now I can boot from qspi and start u-boot. But there are still a lot of questions: 1. TF-A read's flash ID as : INFO: SPI_NAND Detected ID *0xff* 0x2c 0x14 0x2c According to source code it's expecting flash mfr id on zero byte, but 0xff read. Flash type is MT29F1G01ABAFDWB and it has 0x2c 0x14 flash id. Seems that it is not fully correct. After adjusting stm32mp1_boot_device.c in following way: static int get_data_from_otp(struct nand_device *nand_dev, bool is_slc) { uint32_t nand_param; nand_dev->page_size=0x800; nand_dev->block_size = 64U * nand_dev->page_size; nand_dev->nb_planes=1; nand_dev->size = 1024*nand_dev->block_size; return 0; ... I've got following info message INFO: Page size 2048, Block size 131072, size 134217728 and u-boot loads ok It is a strange idea to read QSPI parameters from OTP instead of reading flash parameter pages. I've read https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_overview and know, that ROM code supports ONFI compatible flashes. I'm not expecting that TF-A cant... Sorry for this :( Now u-boot can't load UBI image with following error: ubi0 error: ubi_attach_mtd_dev: failed to attach mtd4, error -22 Please check the attached boot log below.

This is good job !

I/ INFO: SPI_NAND Detected ID *0xff* 0x2c 0x14 0x2c: The issue is from the read_id function from TF-A that does not take into account the Dummy Byte present in this Micro memory for this command. But this has no impact on the behavior because this ID code is not used at all for a Micron memory.

Then, No issue here.

II/ from your logs:

"Loading Environment from UBI... ubi0 error: validate_ec_hdr: bad VID header

offset 4096, expected 2048"

We can see the UBI FS is configured for 4K block size (that is EV1 ST NAND default block size) instead of 2K for your memory. Probably you did not update on Yocto these configurations for your device. After you do that, I think i will be ok.

I will check If I can find the right link to follow but it is self explained at list in Yocto recipe.

[ASkri.1]

Hi, Bernard!

Thank you very much for your reply. Sorry, for very long aswer, I was little busy with other projects... Anyway I've come back, there are some steps forward and still some issues. First, about VID header offset, There are options availabla in machine.cfg file:

MKUBIFS_ARGS_nand_4_256 = "--min-io-size 2048 --leb-size 126976 --max-leb-cnt 1024 --space-fixup"

UBINIZE_ARGS_nand_4_256 = "--min-io-size 2048 --peb-size 128KiB"

EXTRA_UBIFS_SIZE_nand_4_256 = "2304"

So, I can adjust UBI image parameters.

That prpblem WAS, that these parameters are not taken into account until full rebuild, with deleting of build-openstlinuxweston-stm32mp1-duck folder. bitbale -c cleanall not helps... Is it ok? Do you have an Idea how to fix this issue without full image rebiult.

After adjusting parameters that mutch my flash I've got following other error during boot:

Hello,

The variables you modified are not for snand, you need to modify these ones:

./meta-st/meta-st-stm32mp/conf/machine/include/st-machine-common-stm32mp.inc:MKUBIFS_ARGS_spinand_2_128 = "--min-io-size 2048 --leb-size 126976 --max-leb-cnt 4096 --space-fixup"

But how to deal with following variables:
