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

Hi,

I am porting u-boot to blackfin processor. When i try to use serial download (loadb), it hangs in k_recv() - kermit receive. My serial

driver is

fine i guess since its able to accept commands. Its not receiving the START_CHAR becoz of which it doesnt go further to receive any packet.

What may be the problem? Plsss help me.

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

Does everything else work using serial driver?

Did you configure your "~/.kermrc" file as documented in http://www.denx.de/twiki/bin/view/DULG/SystemSetup#Section_4.3. ???

(/root/) C-Kermit>send /home/raj/linux.bin

If not, try the following commands instead:

set speed 115200 set carrier-watch off set handshake none set flow-control none robust set file type bin set file name lit set rec pack 1000 set send pack 1000 set window 5 send /bin /home/raj/linux.bin
