TWR-LS1021A u-boot Issues

Hello everyone,


So i recently started working with the TWR-LS1021A board.

When I received it, It was delivered with a pre-flashed u-boot v2014 and with a 3.12 kernel which seemed to come from SDK 1.1.

I installed QorIQ SDK v2.0-1703 and I successfully managed to build fsl-image-core. I wanted to upgrade my u-boot in order to boot the new kernel image.


However, I connected the card to my host machine through the usb cable on j5 and prompted to the u-boot menu. Due to a faulty manipulation, I managed to erase the flash memory of the board with the u-boot command (I don't remem

I'm not sure how do I recover from this. It seems I can't do anything with the board right now. When I try to start the board, I don't receive anything anymore on my serial terminal. No u-boot message, nothing which seems normal because the u-boot was on the flash memory ...

Can you point me to the right direction on how do I factory reset my board (using JTAG or else)


Thank you in advance for you time.
