[PATCH] Enable Dediprog SF100 programmers with FW 5.5.1
by Pablo Cases 31 Jul '14

31 Jul '14

This patch enables Dediprog SF100 programmers with FW 5.5.1 to work properly with flashrom. The following functionality has been fixed and verified on a W25Q64.V flash chip. All fixes relate to changes in the USB commands issued to the SF100 programmer: * chip discovery (flashrom could not read out the ManufacturerID and DeviceID fields properly, got parts of the devicestring instead) * chip data readout (SF100 issued SPI Fast Read from address 0xF30000 instead of 0x0) * chip data write (SF100 issued SPI Page Program to address 0xF30000 instead of 0x0) * chip erase (verification failed as a consequence of that chip data readout was problematic) * SF100 LED management (LEDs could be turned on but not turned off) Signed-off-by: Pablo Cases <pablo.cases at flatfrog.com> Index: dediprog.c =================================================================== --- dediprog.c (revision 1832) +++ dediprog.c (working copy) @@ -101,8 +101,13 @@ target_leds = leds; } - ret = usb_control_msg(dediprog_handle, 0x42, 0x07, 0x09, target_leds, + if (dediprog_firmwareversion >= FIRMWARE_VERSION(5,5,1)) + ret = usb_control_msg(dediprog_handle, 0x42, 0x07, (target_leds << 8) | 0x09, 0x0, NULL, 0x0, DEFAULT_TIMEOUT); + else + ret = usb_control_msg(dediprog_handle, 0x42, 0x07, 0x09, target_leds, + NULL, 0x0, DEFAULT_TIMEOUT); + if (ret != 0x0) { msg_perr("Command Set LED 0x%x failed (%s)!\n", leds, usb_strerror()); @@ -216,8 +221,22 @@ const char count_and_chunk[] = {count & 0xff, (count >> 8) & 0xff, chunksize & 0xff, - (chunksize >> 8) & 0xff}; + (chunksize >> 8) & 0xff, + 0xFF, 0,0,0,0,0}; + unsigned int count_and_chunk_size; + /* Reverse engineering note: + * ======================== + * Omitting the {0xFF, 0,0,0,0,0} appendage of SF100 FW 5.5.1 + * results in SF100 to incorrectly issue 0x0B (Fast Read) command with + * start at SPI address 0xF30000 instead of the expected address 0x0. + * (On a 8MiB W25Q64.V chip this wraps around to physical address 0x730000) + */ + if (dediprog_firmwareversion >= FIRMWARE_VERSION(5,5,1)) + count_and_chunk_size = 10; + else + count_and_chunk_size = 4; + if ((start % chunksize) || (len % chunksize)) { msg_perr("%s: Unaligned start=%i, len=%i!

Hello Luis, the output of 'sudo lspci -vvxx' and 'sudo dmidecode' would be nice to have. With that we could look for a way to whitelist the board to be not a laptop (as its DMI data indicates erroneously). Although I doubt there is anything to distinguish this board from other similarly crappy boards... :) Apart from that I don't see any problems with the board in the log... as long as you use the correct binary file of the firmware for the board (and always use the -p internal:laptop=... parameter to override the behavior discussed above), flashrom should just work with it. Did you receive a proper binary firmware for the board from the vendor? I am asking because you referred to the flash chip list of fpt a few times but never to any real firmware yet. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Author: stefanct Date: Mon Jul 28 22:35:21 2014 New Revision: 1832 URL: http://flashrom.org/trac/flashrom/changeset/1832 Log: Add new programmer for SPI EEPROMs attached to Intel 82580 NICs. This patch lets you read and write the EEPROM on 82580-based gigabit NIC cards. So far it has been tested on copper NICs only, but other variants employing this controller should work too. It is a nice substitution for the official eeupdate tool. Speed is quite decent: less than 4 seconds for erases or writes of 32 kB.

[PATCH] Add new programmer for SPI EEPROMs attached to Intel 82580 NICs.
by Stefan Tauner 28 Jul '14

28 Jul '14

This patch lets you read and write the EEPROM on 82580-based gigabit NIC cards. So far it has been tested on copper NICs only, but other variants employing this controller should work too. It is a nice substitution for the official eeupdate tool. Speed is quite decent: less than 5 seconds for erases or writes. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda(a)gmail.com> Signed-off-by: Stefan Tauner <stefan.tauner(a)alumni.tuwien.ac.at> Acked-by: Stefan Tauner <stefan.tauner(a)alumni.tuwien.ac.at> --- Rebased on r1831 because that breaks the previous version. Ricardo, if you don't have time or motivation to re-test this then please make a short note. I'll commit this patch then without any tested state, thanks.
