Hi BBB community, We have a BBB Clone hardware with only serial UART as the only communication port to our board at the moment (USB port is not working due to hardware issues)
So this is where I am at this moment, looking for advice to go forward. HW Description: Chip: AM3358BZC100 eMMC: Manufacturer ID: fe, OEM: 14e, MMC version 4.41 Capacity 1.8 GiB Bus Width: 4-bit UART Serial (only I/O to the board) USB (broken due to hardware issues) No SDCard expansion at all. No I2C EEPROM No Nand SW Setup/Progress: Powered up in UART boot mode loaded u-boot-spl.bin via xmodem then after spl is loaded, loaded u-boot.img via y-modem Uboot prompt is alive and working: CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC U-Boot SPL 2013.04-00017-g39e4efe (Nov 20 2014 - 15:53:43) Could not probe the EEPROM; something fundamentally wrong on the I2C bus.

Validating first E-fuse MAC Phy not found PHY reset timed out cpsw, usb_ether Hit any key to stop autoboot: 0 U-Boot# when I do "mmc part" I got an "Unknown partition table" (which is what I expected since this is a bare metal bring up) My goal is to load either ubuntu/debian or angstrom distro onto our BBB clone's eMMC for further application development (and boot from the eMMC) So what are the Next steps for me with UART as the only means communication to/from our BBB Clone to bring up any Linux Distro and flash them including MLO/Uboot to eMMC using only UART? Please advice! Many Thanks in advance!
