I am attempting to move from LTIB to Yocto on a custom i.MX6 SBC. I cannot get u-boot to work yet. I started with the Sabre-SD files and added the customization from the LTIB files that have already been verified. I believe I have two issues:
1. I cannot get anything to display to the console before the MMC line. I would expect to see some text before the first line. I have included a checkboard() function that should output the board name at least. Can't seem to add any debug puts instructions to help. Don't even know if this function is being executed. Here is the console output:
MMC: FSL_SDHC: 0, FSL_SDHC: 1
sd_send_op_cond()
sd_send_op_cond() - 1
Card did not respond to voltage select!
MMC init failed
Using default environment
2. MMC device is failing. As can be seen the MMC initialization has failed. Have not really looked at this yet since I have been focusing on issue 1. Any insights would be appreciated.
I can provide more information if required. Thanks in advance.
