Hi,
No, i am porting u-boot to BF533 processor. The one in blackfin.org is
for BF535. I am able to send and receive characters clearly. Thus i feel the
serial driver is ok.
I tried to send the file using c-kermit. It says too many retries and
fails. I am attaching the statements below. What may be the problem?
LGSI$ loadb 1000 57600
CMD: loadb 1000 57600
444
## Ready for binary (kermit) download to 0x00001000 at 57600 bps...
After set_kerm_bin_mode
os_data_addr = 0x1000
Before ;; for loop calling
(Back at localhost.localdomain)

. As a last resort, give a ROBUST command and try again.

Which port your using? Own or the one from blackfin.uclinux.org?
