Has anybody created an simple project, for the EP9302 or EP9301. This runs without Linux and MMU. I need speed not OS.
Soppurt from Cirrus is supppeeeeeer no answers to the questions. 
Best Regards
If you want speed, you’ll definitely want to enable the MMU. While it’s possible to enable the I-Cache with the MMU disabled, you can’t enable the D-Cache unless you enable the MMU, too.
Of course a simple 1:1 mapping of your SDRAM might be enough.

Hi Dominic,
Thank you for your answer. I have any problems with EP9301 board. I can’t read neither any memory area nor any CPU-Register over JTAG. I have used JLINK with IAR and JTAGJET with Cameleon debugger. :oops: If I remov the JTAG connerctor Linux can boot and sends boot messages to the PC over RS232.
Have you any minds, how can I load any programm to the board over JTAG. :roll:
Best Regards
we created simple projects and have ran code in ram using EW-ARM + JTAG, but to write the Flash over the JTAG special flash loader for EW-ARM must be done which to write in the external flash, it’s explained in EW-ARM documentation how to write custom flash loader but we never had need to do this and use redboot to write EP9301 external flash

Hi Tsvetan,
Where can I download the project. I have buyed your Olimex-ARM-USB-OCD too. I can test it with IAR+JLINK.
Best Regards.
