Reading uses USB bulk transfers without opcodes. This may sound strange, but the SF100 firmware seems to have a builtin mode where it issues the SPI READ opcode (or the FAST_READ opcode, no idea without a SPI sniffer log) if you send a special request without any opcode.

Read seems to work as well. Ack please? Bad news: The dediprog is dog slow. And with dog slow, I mean unbearably sloooooooow. Reading works, but for a 4 MByte chip it may take up to 35 minutes AFAICS, maybe more. The file specified by -r will only be filled with contents after the read is complete. I see a speedup by a factor of 4 on the horizon, but I will implement that only after I get confirmation that read works correctly (would be pointless otherwise). Regards, Carl-Daniel

So if you have a Bus Pirate or any other Sniffer, reducing the SPI frequency to a point where the sniffer can keep up (at least for the first sector or so) would at least reveal the opcode used by the Dediprog. Then I could create an opcode filter which diverts reads to a separate bulk read function. > Frankly, it would still be around 60-100 times faster to always read the > whole chip and just through away what you don't need ;-) > Hm yes.

With 512 bytes per bulk read, this means we have 8192 bulk transactions. That's fast. The flashrom driver uses control URBs for everything: One for sending the opcode, one for reading the result in 4 byte chunks. That means we send 2 million URBs down the wire and receive 2 million URBs. We probably spend 250 µs per transaction on USB 2.0, maybe more. >> sloooooooow.

Reading a chip for 35 minutes and then noticing that the file can't be created isn't exactly nice either. >> I see a speedup by a factor of 4 on the horizon, but I will implement >> that only after I get confirmation that read works correctly (would be >> pointless otherwise). >> >> > Requiring 10 minutes to read the chip is still kind of pointless, so I > don't know if it's worth the effort if the driver can't be generally fixed. > Get me a log of the SPI side (the first 1024 bytes or so are sufficient) with a matching log on the USB side and I can reach the same speeds as the windows driver. As interim measure, I can increase read chunk size to 16 (speedup factor 4) once we know if read works. Once we know read chunk size 16 works, I can test bigger chunk sizes up to 64 (USB protocol limit). That would be a factor of 16 faster than the current implementation. Maybe not perfect, but it would definitely be usable. I need those chunk size tests anyway to implement write support. Regards, Carl-Daniel

Since two different (incompatible) read opcodes exist for most chips, I'd really like to know which one is used by the Dediprog so I can create an opcode filter which redirects the correct read opcode to the SF100 special read function.
