NandFlash support

[relax79]

Hi bvernoux Can you add firmware later x8 and x16 nand support (I read about nand support somewhere in web for this board)? And also add 1-2-3 wire support would be good. I noob but trying MN101EF31G MCU firmvare dumping MCU have a "Clock Synchronous Serial" port 2 or 3 wire adjustable, my board have a 2-wire type programming port, Bus pirate 2-wire is I2C based but I suspect this mcu Full or Half duplex SPI based (bus speed up to 5mhz datasheet). Some people tied MOSI and MISO together for half duplex SPI but one of the pin must be hi-z status other is working condition and other problem I can't understand "AAAh AAh 555h 55h" sequence in flash command table, datasheet says command address = 0x04000 + addr .Command data ? .Can you any advice for firmvare dumping for me or any source link? I am really helpless for this thing and I open couple of thread in forums but nobody help me. Thanks, sorry for my English.

Such feature (NAND 8 or 16bits) Is planned in TODO list but not in top priority (as I'm the only one developer doing this project in my spare time) as there is lot of things to do before, if a developer is motivated (and have time & hardware to test it) I can even provide free HydraBus hardware for such task.

To be supported natively in hydrafw (at least to read/write raw sectors):

• Hynix HY27US08281A NandFlash 3.3V 16Mbyte (x8) (TSOP48)
• Samsung K9F1G08U0C NandFlash 3.3V 16Mbyte (x8) (TSOP48) from http://www.waveshare.com/wiki/NandFlash_Board_(A)

To be supported natively in hydrafw (low priority):

• Samsung S29GL128P NORFlash 56TSOP (x16) from http://www.waveshare.com/wiki/NorFlash_Board_(A)

Not standard bus vs other NandFlash use 16bits Data + up to 22bits Addr (will be not supported):

• Spansion S29GL064A90TFIR4 NandFlash 3.3V 8MByte (x8/x16)
• Spansion S29AL016J70TFI020 NandFlash 3.3V 2MByte (2 M x 8-Bit/1 M x 16-Bit)

Hello , i am understand and thanks for your answer. Some people including me search this type cheap or diy project for usb flash and ssd data recovery(nand programmers are very expensive). These features would be nice if it were. I am so sorry for the delayed answer. Sorry for my English, thanks.

NandFlash support is coming Read ID already work with my Samsung NandFlash (Samsung K9F1G08U0C NandFlash 3.3V 16Mbyte (x8) (TSOP48) from http://www.waveshare.com/wiki/NandFlash_Board_(A)) see https://github.com/bvernoux/hydrafw/tree/flash

HydraBus Reading ID of Samsung K9F1G08U0C NandFlash: Reading ID... 0xEC 0xF1 0xC0 0x95 0xD1

Made some changes in order to get this mode working. Right now, it is possible to read/write 8x NANDs with the patches included in this branch

To test it, you can use this modified version of DumpFlash

Demo :

~/Projects/DumpFlash > python2 DumpFlash.py -i                                                                                                                                                   [master]

NAND 8x mode has been added to hydraFW (https://github.com/bvernoux/hydrafw/commit/5247a8379c008bc5c481aa8afc3f5dc9e2c6a620)
