Blackfin camera console - cp2102

[pchan]

im trying to use the cp2102 si-labs converter, however im not having any success connecting with the blob java console, i only wired up the rx and tx lines, is cts/rts required as well for hardware flow control? has anyone else had luck with the cp2102?

i grounded pin-17 on the srv-1 to disable hw flow control, this did the trick. cp2102 works with just tx/rx connected, thanks all for the info.

from uart.c line starting from 126:
 
void uart0SendChar(unsigned char c)
{
    while (*pPORTHIO & 0x0001)  // hardware serial flow control -
        continue;               //    S32 pin 17 should be grounded to disable
    while (!(*pUART0_LSR & THRE))
        continue;
    *pUART0_THR = c;
}

Exactly.  Note that pin 16 on the 32-pin header is GND, so you just need to connect pin 16 <=> pin 17 to override the hardware flow control.
