AM62A7: SDK 11.1: U-boot: ipc_echo... firmware missing from prebuilts directory

Jonathan Cormier

Part Number: AM62A7

Tool/software:

Previously you could build the AM62A u-boot by pointing the BINMAN_INDIRS variable to the prebuilt-images directory. However in the SDK 11.1 sdk, the ipc_echo_testb_mcu1_0_release_strip.xer5f file is missing or named incorrectly.

$ ls ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/board-support/prebuilt-images/ti-dm/am62axx/
ipc_echo_testb_mcu1_0_release_strip.xer5f  ipc_echo_testb_mcu1_0_release_strip.xer5f.bkp  ipc_echo_testb_mcu1_0_release_strip.xer5f.signed

$ ls ti-processor-sdk-linux-edgeai-am62a-evm-11.01.07.05/board-support/prebuilt-images/am62a-evm/ti-dm/am62axx/
dm_edgeai_mcu1_0_release_strip.out  dm_edgeai_mcu1_0_release_strip.out.signed

The u-boot build instructions still claim you can point to the prebuild-images directory as well.

Looks like according to the yocto u-boot recipe, the instructions should mention setting the TI_DM variable to point to the dm_edgeai_mcu1_0_release_strip.out binary.

DM_FIRMWARE:am62axx = "dm_edgeai_mcu1_0_release_strip.out"
PACKAGECONFIG[dm] = "TI_DM=${STAGING_DIR_HOST}${nonarch_base_libdir}/firmware/ti-dm/${PLAT_SFX}/${DM_FIRMWARE},,ti-dm-fw"

Note the repo listed for cloning the TFA firmware is pretty inconsistent. Not that it matters much but it is a bit confusing.

Two different urls in the SDK docs:

* https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/11_01_07_05/exports/docs/linux/Foundational_Components_ATF.html

git clone https://github.com/TexasInstruments/arm-trusted-firmware.git

* https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/11_01_07_05/exports/docs/devices/AM62AX/linux/Release_Specific_Release_Notes.html
Repo: https://git.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a.git/

And the yocto recipe uses another more official one.
* sources/meta-ti/meta-ti-bsp/recipes-bsp/trusted-firmware-a/trusted-firmware-a-ti.inc

SRC_URI_TRUSTED_FIRMWARE_A = "git://git.trustedfirmware.org/TF-A/trusted-firmware-a.git;protocol=https"
