UART on baffinlite

FYI, since I saw you mentioned "uart wasn't working" in your device notes:

  • I initially screwed up when initially working on the serial debugging guide and accidentally reversed the TX and RX cables, turns out the cable schematics already pointed to tx and rx on the uart board :p try swapping tx and rx on your USB debug cable and see if it works
  • Also, there is no output other than AST_POWERON initially; you have to mash Enter before the "!" appears on-screen, then type "log" and press Enter again, and that should make logs appear. See Samsung_Galaxy_Core_Plus_(samsung-cs02)#Bootloader_.2F_S-Boot_4.0

I was able to make a microusb serial cable and it worked! I'm planning to try porting u-boot as a secondary bootloader (like lk2nd) over the summer. I already did this with mediatek mt6582. Km2 (talk) 18:24, 4 May 2022 (UTC)
