This problem was caused since the apps tried to write to the C123 display, and the display driver couldn't access I2C properly since it had been initialized as UWire on the C155 after we introduced separate images for the boards. I have implemented a simple layer for abstracting the display drivers on both targets, which you can find in my /pending branch. Putting a string on the display now works on both targets with display_puts(); The latest commit in my branch is adding a chip-select for the display which is tested on the C155 and the J100i.
