Hi,
the EA2468 target uses the generic CYGPKG_DEVS_FLASH_SST_39VF3201
flash driver. You should check, if the flash device returns the
proper manufacturer ID (0x00BF) and device ID (0x235B) in function
sst_init() in flash_sst_39vfxxx.inl. Maybe the flash part changed?

Hi Uwe,
Thank you for your quick and kindly reply! I hope this point will help
the followers of the "ea2468" targets.
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
