Hello,
I have olimex arm-usb-ocd JTAG tool and cs-e9302 development board.
I would like to burn redboot image into on board Intel js28f128 strata flash memory.
Cirrus Logic provides with serial port RS232 boot utility with ep93xx series processors, but i do not want to use this utility.
How can i write RedBoot image by using OpenOCD and Olimex ARM-USB-OCD JTAG tool?
Thanks for any Reply…

Hello,
At last, i have managed to overcome how to burn boot loader image into starata flash using openocd.
(svn checkout -r 658 svn://svn.berlios.de/openocd/trunk)
By using these config files and init script, you can acces strata flash via OpenOCD without flash probing failure.
