I am working on imx6q based processor board(Custom). We compiled u-boot and tried to install it on our custom board.  But it's failed. But we tried a u-boot of E9 board and its loaded in our custom board's RAM. Again in that boot prompt also we are unable to give inputs to that u-boot.

I would like to know the reason why my compiled u-boot is not working on my custom board. 

Note:

I am trying to install u-boot of bin file through MFG tool

Board configuration :

Imx6q

1G RAM

UART 1 debug

This is because the correct usdhc settings is not done in  the device tree file

Once I updated that in the device it works for me.

Hi Venkata

for new board recommended first run ddr test

https://community.freescale.com/docs/DOC-105652 

then rebuild uboot with new calibration settings put in U-Boot 2009../freescale/board_name/flash_header.S file

Also as board may use different pads for peripherals, these should be also configured

properly, please check attached Porting Guide. May be recommended to check documentation on

http://www.nxp.com/webapp/Download?colCode=L3.0.35_4.1.0_LINUX_DOCS&Parent_nodeId=133769948107170617... 

Best regards

Hello igarpadykov,

I did the DDR Test and updated the DCD values to the flash header.

And compiled the U-boot. when I load the u-boot using imx_usb ( usb loader ) to my target board. 

load_size 0 bytes
load_addr 0x00000000
dcd 1
clear_dcd 0
plug 1
jump_mode 2
jump_addr 0x00000000
== end work item
loading DCD table @0x910000

<<<-232, 1024 bytes>>>

loading binary file(u-boot.imx) to 177ff400, skip=0, fsize=70c00 type=aa

<<<461824, 461824 bytes>>>
succeeded (status 0x88888888)
jumping to 0x177ff400

But, I load another u-boot of my ready made ( waveshares' E9 Board ) board, then it is showing the u-boot prompt

imx_usb loader log

I am using 1 GB RAM.. And I am using the sabresd board as reference.

I have not change these variables 

  1. CONFIG_LOADADDR
  2. CONFIG_SYS_MALLOC_LEN
  3. CONFIG_STACKSIZE
  4. CONFIG_NR_DRAM_BANKS
  5. PHYS_SDRAM_SIZE
  6. PHYS_SDRAM

But, when my compiled u-boot is jumping to 0x177ff400 and there is not console log. 

 

I am doing anything wrong ?

if your board works well with waveshares' E9 Board, then it is based on

that design. Uboot for i.MX6Q-SABRESD may not work for it,it should be customized

based on E9 Board shematic. U-Boot 2009 works with old L3.0.35 BSPs which

now not supported by nxp. Sources can be found on

Anything wrong in build the kernel ?

After this I am unable to give any boot commands from console. 

Is this any u-boot version issue or am I doing any wrong in u-boot compilation ?
