Hello,

 

I design my own board with an imx28 CPU. I configured the board (resistors on LCD_D0 to LCD_05) to boot on SSP0 (SD card).

 

When I try to boot without SD card connected, I have the 0x8020a014 error code on the debug console. So it seems it want to boot on Sd card. So it's good.

 

But when I connect the SD card, I have absolutely nothing on the debug console.

 

I measured voltage and everything is good except VDD4P2. It equal to 0.8V !!!!!

 

This is the schematic :

Can you help me ?
