I failed to reflash the tailor-made TK1 board

I used Tegra K1 chip to make a board, and now I tried to use the L4T package downloaded from NV official website to reflash the board in the recovery mode, but I failed to reflash the board. The error information was bootloader download failed. How to solve it? Please kindly advise me .

Hi, which DDR chip are you using? The BCT file you used is H5TC4G63AFR, so is your DDR? Please also check the strapping pins setting in TegraK1_Embedded_Design_Guide.pdf to see if any violation on the RAM_CODE or BOOT device selection.

Hi teslalady,

Have you clarified the cause and resolved the problem?
Any result can be shared?


Also don’t forget that using a VM for the host very likely causes USB failures.
