Some additional erors captures. On more event of truncated CAN frame. This time 8 data bytes (instead of 64 are received). So much to my 20 bytes observation ... And then two cases of "Transmit Event FIFO buffer full" along with the requested coredump. Data sent to the gurus personally. If anybody else want to browse through 10 ms of exiting SPI waveform, just ask! -- Stefan
