Custom board LS1012A

Hello,

We have made a custom board using LS1012A processor. We have loaded the RCW and uboot files to the flash referring to the below post. We have used Hardcoded RCW to load the files.

https://community.nxp.com/t5/Layerscape/QSPI-Flash-update-failed-LS1012ARDB/m-p/1420034

fl_unprotect 0x0 0x4000000
fl_write 0x0 bl2_qspi.pbl --erase

fl_write 0x100000 fip_uboot.bin --erase

The files loaded successfully to the flash. After that we removed hardcoded RCW jumper (Connection to GND) and changed the USE_SAFE_RCW from True to False, but the jtag is not able to detect the board after this. Its only detecting the board with the hardcoded RCW changes. We are getting the below error:

Probe: CodeWarrior TAP

Additional error details:

[CCS: TAP USB open failure]

fail to start programming services.

We also tried with code warrior tool to check the DDR validation and it throws the same Target initialization error.

Do we need to perform any other steps after this?

Thanks in advance

Hi,

I checked the u-boot logs. The device is getting stuck at one point. Please find the logs below. Could you please suggest what causing this issue? I have loaded the ardb prebuilt files to the board.
