Is the timeout a watchdog timeout or some communication freeze?
I suppose, it reports false-positive timeout back to ymodem code.
Because all it does is terminating communication gracefully (with 'C'
and a bunch of CANs).
If you are using omap_wdt then check the configured value of the timeout (WDT_HW_TIMEOUT). Time the y-modem loading, and if the reset happens just after that configured value, it would indicate that the watchdog is not kicked, for one reason or another.
