UUU tool working in i.MX 8MM but not in i.MX 6UL

[danie007]

Hi,

We've tried flashing i.MX 6UL with UUU tool and it's not working on closed i.MX 6UL (ref: #235 ). However when we try to work on i.MX 8MMini EVK from NXP, UUU tool works seamlessly on closed device. So, we would like to know the reason and workaround for making UUU work with closed i.MX 6UL.

Feel free to revert for any details. Thanks in advance.

after failure, please use below command to dump log buffer

uuu sdp: RDMEM -addr 0x00901D18 --format 32

...

total 64 words. (0x00901E14)

Hi @nxpfrankli ,

after failure

Thanks for the quick update. I ran the commands you mentioned above (I had to change --format to -format tho) after I kill my script (about 1 min) as my script tends to hang indefinitely.

RESULTS:

uuu sdp: RDMEM -addr 0x00901D14 -format 32 -> Value of address 0x00901D14: 0x00010001

uuu sdp: RDMEM -addr 0x00901D18 -format 32 -> Value of address 0x00901D18: 0x000200CC

The below screenshot is captured after running the above commands.

Feel free to revert for more details.

@nxpfrankli Would you mind elaborating the steps?

One colleague is working on 7d with similar problem. Still not figure out the root cause.
