Zero no longer boots eMMC / SD Card

#1

Hi I have a couple of zeros with eMMC, and using, but one of them suddenly no longer boots.

The MASKROM mode seems working as I could use the RZ_USB_Boot_Helper_V1.0.0 tool to flash the *.bin file into it. However, either the erase bin or the udisk bin won’t work. Won’t work in the sense that no USB storage device is discovered after the flash.

To verify further, I flashed a SD card ubunter server image to plug in. It doesn’t boot as well. The green LED is on.

What could be the possible cause here? In the meanwhile, I am trying to attached a serial and put my output here.

Here is the serial output once pluged-in, with SD card mounted.

Your board might have some hardware problem. Can you take pictures on both side of your board so we can have some visual examination?

OK I didn’t see any major part missing, which could happen to the naked board. Can you try loading Android bootloader and send the serial log? This one has a different memory training profile, and will show up as a fastboot device if the bootloader can load successfully.

#6

Got the two units back and checked,

NO. 04: CPU is burnt, replaced a S905Y2, the board is fully functional now.
