Firmware 0.3.2-pre1
Pre-release
Test build — one file for every Xteink. This image auto-detects X3 vs X4 at boot (I2C fingerprint, same approach CrossPoint uses), so there is no longer a wrong file to flash. It also writes an optional boot log to the SD card for remote debugging.
Flash: unzip, put update.bin at the root of the microSD card, flash the way you always do (CrossPoint's SD update picker or the side-button+power update screen). Works identically on X3 and X4.
Boot log (only if we asked you for one): before flashing, create an empty file named exactly boot-trace.txt at the root of the card. Boot the device, wait 3 minutes even if the screen looks stuck, then put the card back in your computer and send us the contents of boot-trace.txt.
Known not-fixed in this build: the crash when paging into a new chapter of very large books (fix is merged next release), and the X4 shelf missing a book when the library is large. Recovery from any bad state: SD-flash any older release (or CrossPoint) the same way.
