Hi,
We have a custom imx8mm6 board. The first time, we tried to boot with SD but we saw no outputs in LCD (connected with MIPI flat).
- We checked the schematic of the board and found that the BOOT_Mode:[1:0] related pins are connected to the nowhere.

- We prepared the image in different approaches: 1- Pre-built images in nxp page, 2-Built using build-root, 3-Built using yokto project. Tested all but still no results.
- We pulled up the BOOT_1 pad so to have BOOT_MODE becomes 0b10. Still no results!
- We tried to connect to the serial console connected to UART_2, however no outputs there (absolutely nothing)
We want to debug and find the root cause of the problem and how to solve that?
- Moreover, we guess that maybe the ROM log event can guide us to find the issue. However, we don't know how to get access to this log event.
- We can connect to the JTAG via JLINK and all the chains are identified along as Cortex-A53 and Cortex-M4.
- Also, we was able to were able to read some information. But we don't know how to trace the ROM event log.
