I bought Omni3576 evaluation board. After booting up, the LED does not blink. When I connect the board and open RKDevTool v3.31, it shows "Found One MASKROM Device". I tried to download the latest image Luckfox-rk3576-buildroot_250301.img to the board. The log screen always shows:
Download Boot Start
Download Boot Success
Wait For Maskrom Start
Wait For Maskrom Fail
What is the possible reasons for that? How can I troubleshoot it?
