Hi,
I have interfaced an LCD with SPI1 of DM355 EVM board. I have written a small SPI client driver to configure my LCD controller registers.
The problem I am facing is :
I can send the data properly over SPI1_SDO line.
But I never receive any data on the SPI1_SDI Input line. I tried shorting the SPI1_SDO and SPI0_SDI lines to do a loopback test.
I also tried the SPI controller internal loopback test(by setting LOOPBACK bit in SPIGCR1 register). Enabled the SPI Debug macro.
In this case the SPIBUF and SPIDAT1 register dump also show that data is being sent properly .. but received data is always 0.
Anybody faced this issue ?
Any ideas/pointers will help.
Thanks,
Snehal
