AWR1642: can_sbl can't work because MCAN PED error

Hello,

lab0012_can_sbl upgrade fail in AWR1642 + PeakCAN-USB FD suit.

MCAN_IR register always show PED error(Protocol Error in data Phase), it look like that MCAN bit timing(PropSeg/Pseg1/Pseg2/Sjw) have problem.

AWR1642's MCAN configure shall be OK because I also used another RPi3 + socketcan, which normal bitrate is 1Mbps and data bitrate is 5Mbps, to send CANFD frames into AWR1642. Receive is correct that CANFD_getDATA() get correct data without any error.

    Hi,

    The "lab0012_can_sbl" is for the AWR1843.

    Have made modification on this code to support for the AWR1642?

    Hi Raghu,

    Yes, some modifications have applied to build pass for AWR1642.

    The PED error have resolved after turn on PeakCAN's CAN FD ISO-mode. now CAN_Metaimage_Flasher.exe is able to transmit CANFD frames into AWR1642.

    But AWR1642 always show two error failures - RPRC Parsing Failure or Authentication check failed randomly, and the received size are always different.

    Debug: Start the image download using XMODEM over UART Or Hit 'Space Bar' to start Image download ove CAN interface
    CCCCCDebug: Total data written = 0x32d00
    Error: RPRC Parsing Failure!!!

    -------------------------------------

    CCCCCCCDebug: Total data written = 0x36bc0
    Error: Authentication check failed!!!

    It look like that transmit too fast to make CANFD frame lost, any idea?
