I am able to detect the correct Manufacture ID and device ID with these changes.
Bank # 1: CFI conformant flash (8 x 8) Size: 64 MB in 512 Sectors AMD Standard command set, Manufacturer ID: 0x89, Device ID: 0x7E2301 Erase timeout: 4096 ms, write timeout: 2 ms Buffer write timeout: 5 ms, buffer size: 1024 bytes
But the 1024 bytes buffer size is another issues, as Numonyx CFI wrongly mentioned 1024 instead of 256. Any way that we can fix I guess for N29EW flashes..
but how these changes impacts the other flashes i don't ..
Please find the log message.
I made a fix for hw cfi issue when device is operating in 8-bit mode, If the above changes are looks fine we may have this fix will solve the M29EW flashes operates under 8-bit mode.
Could send your comments/views.
Not sure if I understood you correctly. So I have to ask some questions:
Firstly, apologies from my side by sending too many status updates that makes you confusion.
Did you use this patch?
Yes, I have applied the same patch,
http://patchwork.ozlabs.org/patch/140863/
Did it apply without issues to mainline U-Boot? Or did you have to make some changes so that it can be applied? And did it fix the issues you have seen before?
I have manually applied those changes as the index values are differ. I haven't added any newly code other than the patch changes.
Yes it fixed the error by detecting correct manufacture and device ID.
And did you have some make some further changes as well?
And apart from these patch change, I have changed one more this for numonyx M29EW fix for incorrect write buffer size..any way that I could send once these changes are pushed/reviewed.
Thanks, Jagan.
Thanks, Stefan
