imx8mq_m4_TCM_hello_world.bin with Thud

[francesco_giust]

Release: Yocto-Thud ( kernel 4.19.35 )
Board: i.MX8MQ EVK

Hello,
I am checking Thud release and I would test M4 example, but I have a problem.
When I try to load imx8mq_m4_TCM_hello_world.bin in u-boot, I get this message:

u-boot=> fatload mmc 1:1 0x7E0000 imx8mq_m4_TCM_hello_world.bin
** Reading file would overwrite reserved memory **

should I use another address ?

I already test on Yocto-Sumo and there it works fine.

Best Regards,
Francesco Giusti

I have this issue too:

Have there been any updates to this issue? I'm running into this very same issue on the iMX7D chip. One day I was able to fatload to the TCM and now I can't fatload to any address without getting the reserved memory error.

Even if it's not a solution is there a way to figure out what already has the memory reserved?

I am on a mx8m and I got the same issue. "Reading file would overwrite reserved memory" on 4.19.35_1.1.0. I did the following to load the TCM M4 program and it worked :

fatload mmc 1:1 0x48000000 imx8mm_m4_TCM_hello_world.bin

cp.b 0x48000000 0x7e0000 20000

bootaux 0x7e0000

Hi Francesco,

Until now, the most recent Linux version included on the supported NXP BSP releases is L4.14.98, so 4.19.35 is not tested/validated yet.

In case of using other Linux versions, you could refer to the Community BSP:

FSL Community BSP 

Hope this will be useful for you.
Best regards!

Hi Carlos,

I do the same test with imx-yocto-L4.19.35_1.1.0 ( U-Boot 2019.04-4.19.35-1.1.0+g4d377539a1 ), but I get the same result:

u-boot=> fatload mmc 1:1 0x7e0000 imx8mq_m4_TCM_hello_world.bin
** Reading file would overwrite reserved memory **

Should I use an other memory address ?

BR,

Francesco

Got same problem on L4.19.35_1.1.0 warrior on imx7sabre board for command:

=> fatload mmc 0:1 0x7F8000 imx7d_sabresd_m4_TCM_helloworld.bin

** Reading file would overwrite reserved memory **

Did you solve it?

Thanks in advance.
