Not yet a fix for this ? To try hardwire chip in 8 bit mode ? What do you think ? I can use an unused GPIO of pxa to enable via software to control the DoC 8/16 bit enabler pin if i want to have control over this. > > Search the mail-archive for a thread with the subject "[PATCH]Probing at > 0x0" but, the probing issue is solved for me by hardcoding in docprobe.c to probe address "#elseif _arm_ 0x00000000" in docprobe.c, but of course the patch is a more elegant solution. > > The solution is proposed in the thread I see only patch for the 0x0000000 probing issue [already hardcoded for me], but my problem is that it see a 2GiB instead of 32MiB, is this still becouse you tell DoC is in 16bit and driver try 8bit access ? What that mean ? What can i do to figure out this ? Please, let me clarify more a little bit. PS As hardware knowleger, can tell someone if there exist another more popular flash device [i am somehow getting sick about DoC and M-Systems] but to be pin-pin compatible with this device MD-2811-032 and to work nice with mtd drivers ? > > tglx
