An XT245 with liquid-corroded microSD lines could not read any card, in any
format, with known-good code — the kernel log shows the mmc1 host probing at
400kHz and no card ever answering, while mmc0 (eMMC) is healthy. That unit
turned out to be fully deployable anyway: the player boots FLASH:/autorun.brs
straight from internal storage.
Loading 'FLASH:/autorun.brs'
BSPLAY: https://screentinker.com/player?platform=brightsign&model=XT245
So the card is not the only path, and a dead slot is not the end of a player.
Files go to /storage/flash over SFTP and the player runs them on the next boot.
The first attempt failed because the script hard-coded SD: for its own assets:
it loaded from flash and then could not find index.html. StorageRoot() now
probes for FLASH:/autorun.brs and falls back to SD:, and every path that reads a
sibling file — screentinker.json, offline.html, the crash-dump directory — goes
through it.
selftest/ is the bisect that settled the hardware fault: the dev-cookbook's own
html-starter pattern, so the script is not a variable. When known-good code
failed identically, the medium was proven at fault rather than our port.
