i.MX6DL does not boot.

Hi community,

 

I have a question about i.MX6SDL boot.

Our partner made i.MX6DL based custom board.

However, all of them have been not bootded from SD card yet.

Actually, SD card clock was not output with BOO_MODE[1:0]=10b, and cannot connect JTAG ICE.

In addition, the boards were not enter to serial downloader mode even if BOOT_MODE[1:0] is set to 01b.

Any advice what should we confirm to find the root cause?

 

For your information, the partner don't use MMPF0100, and we have checked the following items are OK.

- Power supply voltage.

- Power sequence.

- POR_B release timing (ERR007926)

- BOOT_MODE[1:0] pull-up/pull-down

- 32kHz and 24MHz oscillating

- BOOT_CFG pins for SD card boot (BOOT_CFG1, BOOT_CFG2, BOOT_CFG4[7] are set appropriate, and other BOOT_CFGx are floating)

 

 

Best Regards,

Satoshi Shimoda
