Hello,
I'm attempting to dump/prob a Micron MT29F2G01ABAGD with flashrom, I believe I have the IC tapped correctly, below is a -VV dump
Probing for Unknown SFDP-capable chip, 0 kB: spi_sfdp_read_sfdp_chunk: addr=0x0, len=2, data: 0xc2 0x42 spi_sfdp_read_sfdp_chunk: addr=0x2, len=2, data: 0x42 0xc2 Signature = 0xc24242c2 (should be 0x50444653) No SFDP signature found. Probing for AMIC unknown AMIC SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Atmel unknown Atmel SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Eon unknown Eon SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Macronix unknown Macronix SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for PMC unknown PMC SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for SST unknown SST SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for ST unknown ST SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Sanyo unknown Sanyo SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Winbond unknown Winbond (ex Nexcom) SPI chip, 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Probing for Generic unknown SPI chip (RDID), 0 kB: RDID byte 0 parity violation. compare_id: id1 0x42, id2 0xc242 Added layout entry 00000000 - ffffffff named complete flash Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on linux_spi. Probing for Generic unknown SPI chip (REMS), 0 kB: compare_id: id1 0xc2, id2 0x42 Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI). === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE This flash part has status UNTESTED for operations: WP The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom@flashrom.org if any of the above operations work correctly for you with this flash chip. Please include the flashrom log file for all operations you tested (see the man page for details), and mention which mainboard or programmer you tested in the subject line. Thanks for your help! No operations were specified.
The ID `0xc2 42` matches what I see when the OS boots nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x24
I believe this IC isn't supported by flashrom, how am I able to support it? I have a datasheet
Any help would be greatly appreciated
Cheers
