When tranmiting packet RX (From PC) and TX (To PC), after a moment (random), the CPU resets. I don't use the Watchdog. This happens either on the STR912FAW44X6 and 47X6. This is not a desired feature. What can happen there? Thanks

It reset during the TX (the last packet before the reset is incomplete).
