Hi there,

I need some help! I'm working on a TS-7200 (166MHz) with 8 mb of NOR 
flash (Intel StrataFlash *28F640J3*).

I erased all the flash and re-bootstraped it. I *manually* (using 
serial_blaster_1.0), wrote ts-bootrom-1.05 and reboot (2 blocks). I can 
now correctly boot on Redboot.

If I'm using the official TS binary: redboot-ts7200-8MBflash-update.bin
That work.
If I recompile Redboot this the sources (ecos-redboot-src.tar.gz) It fails:

RedBoot> fis init -f
About to initialize [format] FLASH image system - continue (y/n)? y
*** Initialize FLASH Image System
... Erase from 0x60660000-0x607c0000: ...........
... Erase from 0x607e0000-0x607e0000:
... Erase from 0x607e0000-0x60800000: .
... Program from 0x01fe0000-0x02000000 at 0x607e0000: Err = b0

Error writing FIS directory at 0x607e0000: Error trying to program

What can be different (timings?) ? I tried to hack the flash program 
function but without success.
Ideas are welcome!

Regards,
Matthieu
