I've received 4 MCIMX6QAICPU2 boards (without SD cards and without base boards).
Using the user guide, I've compiled a image.sdcard file that I've dd'ed into a SD card.
Configuring the DIP switches as specified to boot from a SD card I've plugged a 5v 4A power supply.
Nothing on the debug UART and nothing on HDMI.
I've validated the electrical continuity on the DIP switches => everything is ok
I tried using the mfgtool on windows, I can see the board recognized but the tool blocks on pushing the u-boot.
I also tried with the SPI NOR with mfgtool ==> no success, keep blocking no warning
I even reprogrammed the SPI NOR chip manually with a digital oscilloscope ==> no success, no output
How can I understand what is wrong here because 4 boxes not working in a row is strange.
The only thing I see is the leds:
- one blue next to the SD card socket
- one yellow (STDBY led)
- two greens next to the reset buttons
