AM3352: System hangs after SPL

Part Number: AM3352


Hello,

I am trying to start u-boot on a custom board with am3352. I can succesfuly do software leveling to ddr3. The board is configured for uart boot. After the u-boot-spl.bin is uploaded via xmodem I can see some debug messages I have put in board_init_f and in sdram_init. I think that the ddr3 is initalized ok, because I can write and read correctly after sdram_init. The problem is that the system stops at this point. I can't find where the spl hangs.

I can see debug messages because I enabled the early debug in u-boot menucofig, otherwise I can't see any printf in console.

Does anybody know which function will be called next after board_init_f in spl? Where to look to find the problem? I have also tried after this point to continue with ymodem upload but the ymodem does't start.

Thanks a lot.
