[SOLVED] Porting U-Boot 2014.04 on custom board based on SabreSD

Hi,

 

We are using U-Boot 2009.08 on our custom board currently. The minimum changes that needs to be made (from SabreSD version) so that U-Boot can start is flash_header.S and to set different UART pins (SD3_DAT7 for TX and SD3_DAT6 for RX) in mx6q_sabresd.c.

 

I have done the same changes in U-Boot 2014.04 and I cannot get anything on UART. I`m suspecting that something is not right with DDR parameters. We are using LPDDR2 memory.

 

I`m attaching two files from U-Boot 2009.08 with changes, and files from U-Boot 2014.04 with same changes applied.

 

Have I forgotten something? Is something changed in new U-Boot that I have to modify?
