Request for EON EN25Q32

[pepe2k]

Please, add support for this SPI flsh chip:
EON EN25Q32
JEDEC ID: 1C3016

I found in sources (build 331) that there is already support for EN25Q64 (8 MiB) so it should be easy to add support for smaller version (4 MiB).

Try this , i added the chip.

Something is wrong with verify programming option enabled:

Opened file for writing: uboot.bin (binary hex format), total file size: 65 536 bytes
Address 0x4B7: wrote 0x20 and read 0x0 (24072 mismatches)

Write Flash operation complete!

Data is written properly. After reading I get the same binary.

Edit: nope, write function isn't working properly for this flash.

Let me look into this , and i will post back here soon

 

[pepe2k]

Any results?

 

[D3m0n]

Not yet sorry , i have been very busy.

 

[pepe2k]

In build 331, with manual SPI settings I can program and read this flash chip without any problems.

 

[D3m0n]

Can you tell me what settings you inserted manually

 

[pepe2k]

Sure!
With these settings (I have changed only chip size) I can erase, read and program flash (also with verify option enabled):
