Hi, I am using a customised Beaglebone Black, whose schematics is very close to Original Beaglebone Black. You can say we cloned the Beaglebone black hardware and assembled the board.
Now I used Robert C Nelson's Debian wheezy emmc flasher image sd card to boot it for first time , and wrote the emmc. Then I dumped binary data copied from EEPROM of one of the original beaglebone black's eeprom to the eeprom on this. So, now the issue that i am facing is that, this board will not boot up again from emmc or another sd card that i use, other than the flasher sd card. Then accidently or by chance, i tried to look at its UART0 port from UART port on the other beaglebone black and it booted up as usual. After that i observed that this customised beaglebone black is booting only when the UART0 is accessed on another Beaglebone black or just simply connected to its UART. What can be the problem here ? The emmc flashed on another original beaglebone black is working fine, just this customised board will not boot in the usual manner. I was reading through the minicom output at UART0 for this custom board, it gave some read errors, and also said that mmcblk0boot0 and mmcblk0boot1 does not valid partition table. What are these partitions and is it possible to write or create any partitions on them ? I have seen that they are there on other beaglebone blacks and mmcblk0 changes to mmcblk1 if booted from sd card, I could not understand its function. Is this creating any problem with the bootup ? I suspect the eeprom data also might be causing this error. I have attached the minicom output file for the custom board's UART0 port while it was booting. One more thing, it seems, connecting only DGND and UART0_RX to another board is sufficient to make it boot. So it is reading some data over Uart0, is it to do with eeprom ? Please help.
