[imx8qmmek ][uuu] Download .flash_linux_m4 boot loader fail.

WolsYang — Mon, 17 Jan 2022 09:51:06 GMT

Seems like I should not use this ./build_flash_debug.sh output to pack into flash.bin.

Instead use “build_debug.sh” and “build_release.sh” .

====================================

I try to burn flash_linux_m4 to my imx8qmmek ~~imx8qxpmek,~~ but uuu getting stock.

Here is my step

$ bitbake imx-image-full $ sudo ~/mfgtools/uuu/uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_linux_m4 imx-image-full-imx8qmmek-20220113022912.rootfs.wic.bz2

then uuu will getting stock at

uuu (Universal Update Utility) for nxp imx chips -- lib1.4.182-5-g5397913 Success 0 Failure 0 3:4 1/ 1 [=================100%=================] SDPS: boot -scanterm -f imx-boot-imx8qmmek-sd.bin-flash_linux_m4

But if I download flash_spl, all good but no m4 firmeware : (

~~sudo ~/mfgtools/uuu/uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_linux_m4 imx-image-full-imx8qmmek-20220113022912.rootfs.wic.bz2~~

$ sudo ~/mfgtools/uuu/uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_spl imx-image-full-imx8qmmek-20220113022912.rootfs.wic.bz2

Is there any thing wrong with my flash_linux_m4 file?

i saw yours command seems the same :

$ bitbake imx-image-full

$ sudo ~/mfgtools/uuu/uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_linux_m4 imx-image-full-imx8qmmek-20220113022912.rootfs.wic.bz2

then uuu will getting stock at

uuu (Universal Update Utility) for nxp imx chips -- lib1.4.182-5-g5397913

Success 0 Failure 0


3:4 1/ 1 [=================100%=================] SDPS: boot -scanterm -f imx-boot-imx8qmmek-sd.bin-flash_linux_m4

But if I download flash_spl, all good but no m4 firmeware : (

$ sudo ~/mfgtools/uuu/uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_linux_m4 imx-image-full-imx8qmmek-20220113022912.rootfs.wic.bz2

Is there any thing wrong with my flash_linux_m4 file?

try not use uuu.auto , go into that dir, and use this :

$ uuu -b emmc_all imx-boot-imx8qmmek-sd.bin-flash_linux_m4 imx-image-full-imx8qmmek-20220113022912.rootfs.wic

let me know after try, thank you

i saw yours command seems the same :

Nah my bad, just input error in my post.

I am doing all the command in build/tmp/deploy/images/imx8qmmek.

Here is my record video, as you can see I try to clean build to fix this,

But another show on bitbake, that why I only try burn bootloader in this video.

First I burn .flash_spl, then all good and debud console show up.

Second I burn .flash_linux_m4 and that show on what I mean stock : ' (

what bsp version do you use? did you try the demo images?

I am following up i.MX Yocto Project User's Guide, Rev. LF5.10.72_2.2.0, 17 December 2021.

So I think BSP version is LF5.10.72_2.2.0, 17

Well, demo images works fine.

sudo ~/mfgtools/uuu/uuu -b emmc_all ~/Downloads/imx8/imx-boot-imx8qmmek-sd.bin-flash_linux_m4 ~/Downloads/imx8/imx-image-full-imx8qmmek.wic

I can't understand what wrong with my custom flash_linux_m4 file.

Is there any way I can compare my flash_linux_m4 and demo flash_linux_m4 file?

I had upload my linux_flah_m4 to here.It made by imx-mkimage manually which all the file needed is copy from Yocto.

joanxie — Fri, 14 Jan 2022 06:03:09 GMT

how did you build the M4 images? what's steps? just bitbake or use imx-mkimage? if you use imx-mkimage, pls send the command to me, let me double check it

Re: [imx8qxpmek ][uuu] Download .flash_linux_m4 boot loader fail.

WolsYang — Fri, 14 Jan 2022 10:13:36 GMT

I had try both bitbake and imx-mkimage

For make M4 image , first in MCUexpressoSDK

$ cd ~/imx8qmmek-m4/boards/mekmimx8qm/multicore_examples/rpmsg_lite_str_echo_rtos/cm4_core1/armgcc ./build_flash_debug.sh $ cd ~/imx8qmmek-m4/boards/mekmimx8qm/multicore_examples/rpmsg_lite_str_echo_rtos/cm4_core0/armgcc ./build_flash_debug.sh

In bitbake :

imx-boot_%.bbappend : Replace demo m4 image

do_compile_prepend () { bbwarn "replace origin m4 image" cp ${BSPDIR}/sources/meta-sintrones/recipes-uboot/m4Img/imx-boot/rpmsg_lite_str_echo_rtos_m40.bin ${DEPLOY_DIR_IMAGE}/imx8qm_m4_TCM_power_mode_switch_m40.bin }

bitbake imx-boot -c cleanall bitbake imx-boot -f

In imx-mk-image :

copy all file in /imx-yocto-bsp/build/tmp/deploy/images/imx8qmmek/imx-boot-tools to /imx-mkimage/i.MX8QM/

cd ~/imx-mkimage make SOC=iMX8QM flash_linux_m4 or make SOC=iMX8QM flash_spl

that s good after you modified yours commands

2 your board is imx8qmmek

your title talking abt imx8qxpmek but in command and demo i saw it is imx8qmmek, please be adv that imx8qmmek and imx8qxpmek r difference board, even imx8qxpmek also have some si b0 , si c0 a b a1 b1 a2 b2 and more yah. please clear esp when u try to do advance config and porting jobs , even theirs port, eth, mem address etc many differences .

please make it clear 1st: which board are you currently using it?

i help u compare your bin and official imx8qmmek linux.m4 , see pic, a lots of difference by Beyond Compare App although in bin mode codes.

so confirmed you doing wrong img bin some where

pls strictly fellow nxp guides , quick easy and straight forwards not so difficulty u will done it if u fellow up theirs guides strictly.

if you used bitbake i think there already is a -flash-linux- m4 there

u want customize yours self m4, please go to references user guides please

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8-Boot-process-and-creating-a-bootable-image/ta-p/1101253

it also have ZIP files inside.

solved.

thanks you

./build_flash_debug.sh <<<

Well, I think here is the problem.

I am not sure but seems like I should not use this flash_m4_image to pack into flash.bin.

Instead use “build_debug.sh” and “build_release.sh” to make my own m4_image, right?
