Hello,
I'm trying to port the CEPC sboot code to the XSC1BD platform,
but this don't work.
My platform send "kITL»$¥ØXSC1BD" and "Wait for boot ack..." but
nothing it's received.
Platform Builder is "Waiting for a download request..." indefinitly.
Is this code set RTS ?
UCHAR uCtrl = (READ_PORT_UCHAR(KitlIoPortBase+comModemControl) &
~MC_RTS);
WRITE_PORT_UCHAR(KitlIoPortBase+comModemControl, (UCHAR)(uCtrl |
MC_RTS));
And this clear RTS ?
WRITE_PORT_UCHAR(KitlIoPortBase+comModemControl, (UCHAR)uCtrl);
When I do the same thing by the following code, pDownloadUartPort->mcr
|= 0x2; // Set RTS and pDownloadUartPort->mcr &= ~0x02; // Clear RTS,
my PC stop running when it open then COM port.
I don't impletment the serial KITL, must I do ?
What are the Platform builder Remote connection settings (flow control
or not) ?
Like the Beatles says:
Please, HELP ME !!!
