I have two TI's development boards, TMDXLCDK138. I wrote a module to configure the SPI0's CS , SIMO, SOMI, ENA pin as the GPIO pins . one board is normal. But another board's pins can not get the right logic waves. its registers seem right. but the pins are always low, no output waves.
there are two difference i can find:
(1) the bad board before Simulation must press the key of the reset.
(2)on the bad board the D7 is always light but in the right board D7 is not work.
what is the problem of the board? is it the port of the SPI0 damaged?
