Hi,
can i get authentication failure codes description?
Boot log buffer shows authentication failure 00A1E33. what does this failure means?
I am also adding my complete log buffer for analysis.

00902190 = 00010002 000200F0 00030000 00040000

Hello,

The code is similar to PLUGIN_IMAGE_FAIL (0x000A0033).

For more details, please create request.

Have a great day,

Yuri

hi,
after alot of changes in my binary. I am finally able to get to this state.

Yuri‌
the binary which created above buffer log, does not boot and system goes to serial downloader mode. and i can see my binary placed at entry point.

Also with one of my binary files, after booting from NAND, system does not goes to serial downloader mode BUT i am unable to connect to it via JTAG. J-Link commander generates an error for "unable to halt CPU". Can I say that my system booted up but it crashes immediately after booting (might be due to application I am running on it).

Hello,

looks like the image starts, but does not fully work.

What is Your application?

Regards,

Yuri.

I am trying to boot a customized application right after Boot ROM code handover control to SRAM.
is it possible to skip all cp15 and stack pointer initializations and directly run application? I skipped them when booting from SD-card. I appended IVT and DCD on my binary file prepared a bootable SD card, and my application was successfully running. I am trying to reuse that approach with NAND too. I have appended IVT and DCD on my binary and programming NAND using kobs-ng. kobs-ng itself add all NAND related stuff to binary and program it.

are you talking about the case mentioned with JTAG problem or analyzed the buffer log? because buffer log is created with a different binary, which transfer to serial downloader mode. AND other binary which creates JTAG problem does not enable serial downloader mode.

Hello,

if the same application, that can be loaded, verified and run from SD, but cannot be run

from NAND - perhaps the problem concerns with NAND?
