What I did this week

• The LED device tree overlay is now complete with BBAI.
  • Relay: https://github.com/beagleboard/BeagleBoard-DeviceTrees/commit/d46aa49f43c428902709d8ae0feff2fac2ee330e
• I have started writing documentation on Relay Cape.

Blocker

• I am stuck in the BBAI-64 environment construction.
  • The SD card does not appear to be loaded at boot time.
  • While trying to cope, the UART becomes unstable and cannot be input.

→ I will try to make a barrel jack cable to see if there is still a high possibility of power supply problems.

What to do next

• Create a device tree of LEDs for BBAI-64.
• (Not done this week) Continue to work on the Cape overlay, including I2C and SPI.
