Hi Christophe,
Thank you for your new FLASH driver(s)!
I have one wish.
I would set value for CYGPKG_DEVS_FLASH_SPI_AT25DFXXX_BLOCK_SIZE in
bytes. What do you think? IMO, it is more clear and no need to have
those shift operations in C source.
Ah, two wishes :-)
What is a target that you use with the driver? Is that eCos target? If
it is, could you, please, provide simple test under package's test
directory to give a way to compile the driver? It would be great. I
mean something like this Chris's test
devs/flash/spi/m25pxx/current/test/m25pxx_test.c
About the driver's placement, devs/flash/spi is reasonable place on my
look.
Sergei

Updated patch with sector size defined in # of bytes
Hi Sergei,
I have updated the patch to define the sector size in byte.
The flash is tested with an Actel Smartfusion dev board which is not in CVS. I
have a test case similar to m25pxx_test.c which is located in the dev/flash/ of
the smartfusion board. I'll provide the full BSP when completed.

Thank you. I've added a few SZ_*KB definition there (like those in
hal_misc.h) and cleaned-up sources according eCos coding style. See
interdiff for details.
FYI: in CDL 'active_if' value has been fixed. Typo?
Hope that I've broken nothing. At least driver compiles itself without
warnings.

Great. Could you, please, re-test the update patch (attachment 1265)
then?
Sergei

Thanks Sergei. I will re-test the patch and let you know.
The active_if in the CDL file is copied from the CDL file
devs/flash/spi/m25pxx/current/cdl/flash_m25pxx.cdl

Hi Sergei,
Latest version of the patch is re-tested OK on Actel board.

Christophe, thank you for your contribution to eCos, also for testing
