Hi, If you want to use kerrmit from Linux then I recommend you install the 'ckermit' package. (I wasted a lot of time trying to get kermit to work in minicom, nothing I tried worked. 'kermit' was faultless) Anyway, not only is the kermit client robust but the terminal emulation is better than minicom. You just need a .kermrc in your HOME directory - something like... set line /dev/ttyS0 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 ..and you are done.

I actually used Hyperterminal in windows at the time for Kermit transfer. It just started working right away. I haven't done Kermit transfer in minicom. I'm sure somebody can clue us in.

Hi Josh, Thanks a lot for update. I am trying the kermit mode - I did the following EVM # loadb Ready for binary (kermit) download to 0x80700000 at 115200bps Then in my minicom I did a Ctrl-A Z and choose the uImage in location /uImage After this there is no more activity in the EVM# prompt. Should the uImage be put in some specific path or so? Cheers Deepak ________________________________ From: Joshua Hintze [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2008 9:59 PM To: Deepak Shankar-TLS,Chennai.; davinci-linux-open-source@linux.davincidsp.com Subject: RE: Kernel update through serial port. I'm not sure about the Davinci (I haven't tried yet). But on other projects, using the Gumstix processor, I was able to transfer the kernel using Uboots Kermit serial protocol. I would think you could do the same for U-boot. Josh From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Deepak Shankar-TLS,Chennai. Sent: Monday, September 15, 2008 10:38 AM To: davinci-linux-open-source@linux.davincidsp.com Subject: Kernel update through serial port. Hi, I'm a newbie to both Linux and davinci. Could someone tell me if its possible to update the U-Boot and the Kernel through the serial download. My target board does not have an Ethernet port and it would not be possible to me to do a tftp on it. So the only possibility is JTAG, and I'm interested in onfield upgrades. Please note, I'm not referring to the booting Linux from UART- but to update the U-boot and the Kernel present in the NAND through UART. Do we have to do some tailoring in the U-boot coming with the standard dvevm. Any other pointers are greatly welcome Cheers, Deepak Shankar V DISCLAIMER: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
