IMX6SX - u-boot. mfgtool uuu.

mabar52 — Tue, 10 Oct 2023 12:58:56 GMT

Trying to get an old u-boot configuration from Yocto2.7 to work with Yocto 4.

I get USB timeout when trying to write u-boot image to IMX6SX.

I suspect I miss some config statement for u-boot.
I will also attach my .config.
Otherwise how do I debug this?

Hi @mabar52!

How are you generating your image?

What kernel version are you using?

What command is sending to the uuu to program the iMX6?

For 4.1.15_2.0.0 or lower use MFGTool, UUU is supported in U-Boot imx_v2018.03_4.14.78_1.0.0_ga and later releases.

Best Regards!

Hi, Chavira.

The image is build through Yocto (4) as a bbappend to

2022.10+fslc

bbappend file and include file attached.

it has patches to the Kconf and code.

Kernel is 5.15.87

Ps. I also cloned the u-boot-fslc repo and built it separately from Yocto. That seems to work to write.

I have found a difference in the .configs of a newly built u-boot from freescale repo and ours.

builder@ubuntu-linux-18:~/projects/src/u-boot-fslc$ grep CONFIG_SYS_TEXT_BASE .config CONFIG_SYS_TEXT_BASE=0x17800000 builder@ubuntu-linux-18:~/projects/src/u-boot-fslc$ git remote -vv origin https://github.com/Freescale/u-boot-fslc.git (fetch) origin https://github.com/Freescale/u-boot-fslc.git (push) builder@ubuntu-linux-18:~/projects/src/u-boot-fslc$ git status On branch 2022.10+fslc

Ours:

builder@ubuntu-linux-18:~/projects/src/smartware_master/build/tmp$ grep SYS_TEXT_BASE ./work/smartoptics_dcp-poky-linux-gnueabi/u-boot-fslc/DCP-R8.0-r0/build/smartoptics_dcp_memtest_config/.config CONFIG_SYS_TEXT_BASE=0x87800000 CONFIG_HAVE_SYS_TEXT_BASE=y

Is this changed in recent u-boot. Does it mean an offset instead of absolut address now?

Hi @mabar52!

Please use only the official BSP.

We only have kernels 5.15.71, 5.15.52, 5.15.32.

Please check our Yocto User Guide and try to use our software.
