STM32MP157AAB failed to boot from NOR QSPI (bare-metal)

[Genadi Zawidowski]

Hello.

Can someone explain problem by this diagnostics:

----------------------------------------

bootfailed

S-00000001C040CFFE

NS-0000000000000000

°----------------------------------------

bootfailed

My board say these lines to PA13 pin (9600-8N1) after power up.

Flash memory contain [may be] properly formed first stage bootloader file with only infinite loop at starting point.

Binary in attachment.

(I also send you a message)

some thinks to look for:

• check that the QSPI is connected on the right default pin (see AN5031 or this page)
• Did you have tested with DDR tuning tool (i.e. uBoot SPL running) ? the DK2 uboot SPL provided in starter package is likely to work as-is on your board (as you are using single DDR3L and PMIC), could be loaded with CubeProgrammer with UART connection. see https://wiki.st.com/stm32mpu/wiki/U-Boot_SPL:_DDR_interactive_mode
• Did you programmed the Flash using CubeProgrammer ? https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#Basic_boot_chain_support
• Did your binary contain the right header (required even if no secure boot). See https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot#Image_signing

[Genadi Zawidowski]

Yes, QSPI connected right (if I erase memory or corrupt STM2 signature, I can connect trough serial boot)

No, I not use DDR in my "bootloader" - just infinite loop

No, I use own flash programming tool - in this case Altera's USB byte blaster, CubeProgrammer can not do anything (looks like expecting SD card or something like).

Yes, you can examine my binary by downloading form 1-st message in this topic.

Manual say:

Traces can be downloaded from address range 0x2ffc1c00-0x2ffc2404

But, area from 0x2ffc2400 declared as used for bootloader. Should I move my code?

[Genadi Zawidowski]

Can someone place here compiled "DK2 uboot SPL" - I can flashing this file and connect trough.... Serial port? What pins/speed?

[PatrickF]

seems your binary has wrong size declared somewhere (maybe in the header) as if I try to flash it on the Serial-NOR of an STM32MP157C-EV1 board, I get

Message from Embedded Flash Loader : fsbl1: Bad size requested for partition 1 = 0x4000000 <> 0x40000

As the FSBL is loaded in SYSRAM, size is limited to 0x2ffc2400 to 0x2fffffff, so must always fit into a (fixed size) partition of 0x40000

[Genadi Zawidowski]

Size form 2ffc2400 to end of this region is 247 KB - it is 0x3DC00‬, not 0x40000. I use seriously less size:

[Genadi Zawidowski]

Can you form right image header for this sample file?

Loading address and entry point - same value 0x2ffc2400

[PatrickF]

Your binary sound well formed.

Note that there is a typo in the wiki (not so important), you should read : Traces can be downloaded from address range 0x2ffc1c00-0x2ffc23ff

Could you explain the following sentence you wrote "Yes, QSPI connected right (if I erase memory or corrupt STM2 signature, I can connect trough serial boot)"

This mean your binary is loaded and started, right ?
