Hello!
Any updates on the topic?
I'd like to point your attention, that 'pcsendpkt' program from mcsdk_2_01_02_06\tools\boot_loader\examples\ethernet\Ethernet_boot\ does contain a large useless loop in the code between sending consecutive frames. That makes me suspect some gap is required, but not documented. Here is a piece:
/* add delay between packets */
for(i=0; i<DELAY; i++) {
tmp4 = tmp3;
tmp3 = tmp4;
}
