Hi,
this has been put aside for a while but tested this again and problem still remains for me.
Hi,
I'm following the README to bring up u-boot on a imx8mp EVK board. My boot ends up in this on the console:
U-Boot SPL 2020.10-rc5-00049-gd44d46e9fa (Sep 30 2020 - 11:46:20 +0200) Normal Boot WDT: Started with servicing (60s timeout) Trying to boot from BOOTROM image offset 0x8000, pagesize 0x200, ivt offset 0x0 Can't support legacy image SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###Any ideas what is going wrong? How to debug further?
I am trying to port U-Boot to an i.MX8M Nano and I am getting the same result.
This might not be related, but looking at the ATF branch [imx_5.4.3_2.0.0] - it appears to be too old, at least for i.MX8M Plus. I was able to run the U-Boot 2020.10 with ATF built from [imx_5.4.47_2.2.0] on the i.MX8M Plus and it does boot successful.
Boot log show the following banner when BOOTROM finishes up the copy: NOTICE: BL31: v2.2(release):rel_imx_5.4.47_2.2.0-0-gc949a888e-dirty NOTICE: BL31: Built : 05:51:50, Sep 9 2020
Peter, i.MX8M Plus support in NXP ATF fork appears to be added by commit https://source.codeaurora.org/external/imx/imx-atf/commit/?id=6b8249ff58cc88..., and that came in ATF revision far newer than indicated in doc/board/freescale/imx8mp_evk.rst
Try to rebase your ATF to [c949a888e909811db191500c51456391dff61284] and build according to the board doc file.
Andrey, Thanks for advice about the commit in imx-atf. Unfortunately it does not seem to solve the issue.
This is what I tested today and where I ended up today:
$ cd imx-atf $ git checkout imx_5.4.70_2.3.0 $ make PLAT=imx8mp bl31 $ cd ../u-boot $ git checkout master (80c7e4cf76d204d4b726b0cc57a557a9d9c1c453) $ cp ../imx-atf/build/imx8mp/release/bl31.bin . $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_202006.bin lpddr4_pmu_train_1d_dmem.bin $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_202006.bin lpddr4_pmu_train_1d_imem.bin $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_202006.bin lpddr4_pmu_train_2d_dmem.bin $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_202006.bin lpddr4_pmu_train_2d_imem.bin $ export ATF_LOAD_ADDR=0x960000 $ make imx8mp_evk_defconfig $ make flash.bin $ sudo dd if=flash.bin of=/dev/mmcblk0 bs=1024 seek=32
When booting on a imx8mp EVK from NXP the console shows me this:
U-Boot SPL 2020.04-00033-g633977d904 (Feb 12 2021 - 08:12:50 +0100) DDRINFO: start DRAM init DDRINFO: DRAM rate 4000MTS DDRINFO:ddrphy calibration done DDRINFO: ddrmix config done Normal Boot Trying to boot from BOOTROM image offset 0x8000, pagesize 0x200, ivt offset 0x0 Can't support legacy image SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
The code that fails is in arch/arm/mach-imx/spl_imx_romapi.c
if (IS_ENABLED(CONFIG_SPL_LOAD_FIT) && image_get_magic(header) == FDT_MAGIC) { .... } else { /* TODO */ puts("Can't support legacy image\n"); return -1; }
I have traced out 'image_get_magic(header)' on the console and it is a new random value at each power on. I can also note that I have tested branch imx_v2020.04_5.4.70_2.3.0 from from uboot-imx ending up in the same result on the console.
Anyone that have ideas here how to proceed and where the problem can be? Anyone with a imx8mp EVK on the desk that succeed with building and deploying u-boot on a SD card and can share the workflow?
Best regards, /Peter
