We have designed a custom version of Beaglebone Black with most of the schematics being same.
The board is assembled and we are able to get its PMIC work ,Power Led is working and we measured the voltages, they are in agreement with the datasheet of TPS65217C and BBB_SRM. The next step naturally would be to boot this board with a sdcard.
Since we have used sd cards with debian on them with Beaglebone Blacks ( refering to : http://wiki.net/display/linuxonarm/BeagleBone+Black ) , we considered trying it with this board too. Looking online as to how to boot our board with that same sd card, we discovered that the eeprom on beaglebone black will pose a problem and indeed we did not see any activity by trying to power up the custom board with sd card having debian that works well with beaglebone black.
The eeprom is empty. Online forums suggest two ways, either block eeprom access over i2c in uboot or write the requisite code in eeprom while in uboot. If we can get access to the uboot shell over its UART0 , we can manage.
Can we be guided/helped or some pointers be given as to how do proceed forward and get our custom board working ?
