I had better luck with ymodem than kermit when using minicom. Use loady
and send the file similarly. Make sure the ymodem binary is available
as well. Minicom may not give you an error even if it is not installed.

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

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.

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
