Hi, sergei,
I am still struggling with flash problem in EA-2468 board.
In this mail, you mention that Youqiang Zou added
CYG_FLASH_DRIVER definition to flash_ea2468.c. Can you explain me detail?
Should I add same definition for my board??
Thanks,
Viren

Hello Uwe,
FYI: Youqiang Zou sent me an information and his own snippet. He added
CYG_FLASH_DRIVER definition to flash_ae2468.c. May be that's it, because
then I saw such an entry in SST ChangeLog
2008-11-17 Jonathan Larmour <drop his email address>
* cdl/flash_sst_39vf400.cdl:
Don't implement CYGHWR_IO_FLASH_DEVICE here. Leave it for
the chip driver.
... and this was happened after that you had distributed your port.
I asked him to send a patch in the eCos patches list. Thus I did not see
Zou on the eCos lists. In any case that is something likes a thing is
under "10-lines" limit.
Regards,
Sergei
