I am struggling very much to kick start my BBB rev C. When I power ON the board it does not boot, cant see user LED’s blinking. Its only booting when SD card is inserted and press and hold user button and power ON. I tried almost all the methods such as 1. Debian flasher image, 2. Debian sd card image 3. I tried Debian: Getting Started with the BeagleBone Black - Linux Guides - Engineering and Component Solution Forum - TechForum │ Digi-Key but nothing is working. It also takes more than 7-8 minutes to boot from SD card dont know why?. I suspect problem in NAND flash but how to fix it dont know. please help me out from this. Thank you very much
Please find below the logs for Debian SD card 10.3 image

I have flashed above image successfully, BBB turned Off automatically. Then removed SD card from socket and powered On BBB. Power indicator is turned On but User LED’s are not turning On in any pattern. I waited for long time but nothing is happening. Unfortunately I am not able to attach serial logs here. Getting new user can post only 2 links issue.
