Hey guys
I already had made u-boot for my evaluation board and it was OK!
Now I want to port the same boot loader on my own custom board which has different structure.
Instead of 64 Mb SDRAM of standard board my board has a 128 Mb SDRAM and this board uses SDRAM bank 1 instead of bank 2 in standard board. Also my board uses a 12 MHz external oscillator instead of 8 MHz in evaluation board.


I change the settings but I see:


U-Boot 2010.03 (May 29 2017 - 10:12:45)


CPU  : --- 
Freqs: SYSCLK=180MHz,HCLK=180MHz,PCLK1=45MHz,PCLK2=90MHz
Board: STM32F429II-SADR board,Rev 1.0
DRAM:   8 MB
Using default environment


  R0    = 90700000  R1  = 00000000
  R2    = 00025800  R3  = 00000004
  R12   = 000257fc  LR  = 08005a23
  PC    = 080007ea  PSR = 21000000


and the below line doesn't appear:


Hit any key to stop auto boot: 0


I changed delay time to 3 sec but the result was same and u-boot doesn't start boot!!!
I would be thankful if you tell me what is the problem with my configuration.
