[U-Boot-Users] ocdemon for initial u-boot flashing?
Good evening..
Small off-topic question (o;
Someone using OCDemon flash programmer for initial flashing of u-boot to a 8260 board?
Installed the demo version and it keeps saying that it can't run target code...or is unable to write to RAM location...
Was only once able to erase an existing old firmware...but that's all. Seems it needs some more initialisation than those offered in the software...
Wrote a simple jtag flash program for Linux/Windows to do JTAG flashing but it takes some time for programming though (o;
thanx for any hints rick

Hi Marcel...
Know this link (o; but never tried...
Any comments about the speed?

It depends on parallel port hardware speed, flash memory organization and boundary scan register (BSR) length.
My today's experience: - JTAG adapter: simple parallel port dongle - Oxford Semiconductor Ltd VScom 011H-EP1 1 port parallel adaptor (fastest than my standard parallel port on MB) - a part with BSR length > 500 - flash memory (intel strataflash) 1 x 8 bit width - flashing speed (it includes verifying): about 22 minutes per block (128 KiB)
For 32 bit flash organization the speed should be about 6 mins per 128 KiB.
Have a nice day.

I tried this once since I used the Wiggler successfully on an MPC860 project. I couldn't get it to work. Could not get support. Bought BDI200 and have no problems.

Seems to be half way workig only if some firmware is already in the flash doing the neccessary initialisation...never works with an empty flash though...
Switching to jtag-0.5.1 from openwince project...looks very good and Marcel is already doing a PPC port (o;
