Intel P30 flash. OTP write error

[CartmanYO]

Hello! I have a problem with writing OTP registers. I receive the following message:

flash device: word write error (status 0xb0)

I use linux kernel drivers (v. 2.6.22). 0xb0 status means command sequence error (bits 7,5 and 4 are set). cfi_cmdset_0001.c driver is used for my intel p30 strataflash. I checked everything i could, but no solutions found. The driver seems to work well cuz first it sends 0xc0 command to initiate OTP programming mode and then writes word at specific address. But after checking the status register error occures - 0xb0.

I found solution. Maybe it would be interesting for someone. 0x80 - WORD address of first lock register, for top-parameter devices (like p30) we have 0x3F0080 WORD address. So, to calculate real address we need to multiply it by 2, and the address would be 0x7E0100.
