[PATCH] Add support for SST25VF512A
by Cory Henderson 15 Oct '13

15 Oct '13

Hi, I am new to the mailing list so I am not sure if this is the right place for these. My company used the SST25VF512A in a project and I was able to configure flashrom to work with this chip using a buspirate (HW v3.5, FW v6.2 beta). The chip was already listed in flashchips.h so I just added the proper information to flashchips.c. Probe, read, write, and erase all work fine for me, albeit slowly because the AAI supported by the chip uses a different command than the one used in flashrom. Cory Henderson

Phonenix_efi bios flash map
by Ricardo Ribalda Delgado 14 Oct '13

14 Oct '13

Hello I have a board that uses a phoenix_efi secure core Tiano BIOS. I can read and write it properly using flashrom. Good work guys! Unfortunatelly every time I reboot the machine, I read back a different content of the flash. I guess there are some variables that the bios set on boot. Is there a way to get a "bios map" of what areas are code and what areas are data? I want to monitor if the flash is corrupted. BTW. Anything I could do to help merge the nic_intel_eeprom patches? Regards! -- Ricardo Ribalda

[PATCH] serprog: optimize serial buffer handling
by Urja Rannikko 14 Oct '13

14 Oct '13

Now we remember the size of each sent command, and allow us to continue when enough ACKs have been received, instead of all the ACKs. This is done with an internal FIFO storing the sizes. Signed-off-by: Urja Rannikko <urjaman(a)gmail.com> ---- Note: I did calculate that the maximum FIFO size (memory allocation) that the device can make flashrom do is 256k - 4 bytes. I think this is acceptable, and makes the code overflow-proof. Also, since SPI API could TX a command over 2^24 bytes long (7+(2^24-1)), we use uint32_t's to store the size so it will always fit. --- serprog.c | 92 +++++++++++++++++++++++++++++++++++++++++++++++++++------------ 1 file changed, 75 insertions(+), 17 deletions(-) diff --git a/serprog.c b/serprog.c index 03963ec..89affab 100644 --- a/serprog.c +++ b/serprog.c @@ -75,6 +75,9 @@ static uint32_t sp_write_n_bytes = 0; /* sp_streamed_* used for flow control checking */ static int sp_streamed_transmit_ops = 0; static int sp_streamed_transmit_bytes = 0; +static uint32_t * sp_stream_txop_sizes = NULL; /* Size: ..._serbuf_size * sizeof uint32_t */ +static int sp_stream_txop_wroff = 0; /* Used when sending. */ +static int sp_stream_txop_rdoff = 0; /* Used when receiving ACKs */ /* sp_opbuf_usage used for counting the amount of on-device operation buffer used */ @@ -204,8 +207,28 @@ static int sp_automatic_cmdcheck(uint8_t cmd) return 0; } -static int sp_flush_stream(void) +static void sp_stream_add_txop(uint32_t size) +{ + sp_streamed_transmit_ops += 1; + sp_streamed_transmit_bytes += size; + sp_stream_txop_sizes[sp_stream_txop_wroff++] = size; + if (sp_stream_txop_wroff >= sp_device_serbuf_size) + sp_stream_txop_wroff = 0; +} + +static uint32_t sp_stream_rm_txop(void) { + uint32_t size = sp_stream_txop_sizes[sp_stream_txop_rdoff++]; + if (sp_stream_txop_rdoff >= sp_device_serbuf_size) + sp_stream_txop_rdoff = 0; + sp_streamed_transmit_bytes -= size; + sp_streamed_transmit_ops -= 1; + return size; +} + +static int sp_stream_free_bytes(uint32_t need_freed) +{ + uint32_t freed = 0; if (sp_streamed_transmit_ops) do { unsigned char c; @@ -221,7 +244,37 @@ static int sp_flush_stream(void) msg_perr("Error: Invalid reply 0x%02X from device\n", c); return 1; } - } while (--sp_streamed_transmit_ops); + freed += sp_stream_rm_txop(); + if (freed >= need_freed) break; + } while (sp_streamed_transmit_ops); + return 0; +} + +static int sp_verify_stream_free(uint32_t size) +{ + /* Allow for device accounting "error" of 1 byte.

[PATCH] serprog: add proper serprog_map

Add serprog_map so that chips are addressed properly. I did this for adding LPC support to my ATmega644 programmer.

I think you just need to use google's fork of flashrom. Unfortunately both branches of flashrom diverged quite a bit since then... -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Flashrom with Serprog/Arduino on nano v3
by flashrom＠secure-proxy.org 12 Oct '13

12 Oct '13

Hello, i try to read SPI flash from a bricked wifi access point. For that purpose I have unsoldered the 4M SPI flash, soldered it onto an ssop-breakout board where I connected it to an Arduino-Nano. I use flashrom out of my ubuntu distribution, and compiled serprog-duino myself. Running flashrom to detect the device works as expected: ------------ $ flashrom -p serprog:dev=/dev/ttyUSB0:2000000 flashrom v0.9.5.2-r1517 on Linux 3.2.0-54-generic-pae (i686), built with libpci 3.1.8, GCC 4.6.3, little endian flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. serprog: Programmer name is "serprog-duino" Found Macronix flash chip "MX25L3205" (4096 kB, SPI) on serprog. No operations were specified. ------------ However when I add the "-r filename" Option, to read the content of the flash, the program get stuck. I tried the master and the ftdi-branch from serprog-duino [the only difference is, that in the ftdi-branch the 10us delay is missing], with no difference in behaviour. I tried both versions with both cabling-recommendations: firsthand with the resistors as voltage-dividers, than with direct 5cm cables. In all combinations flashrom is hanging during a read-statement. The strace looks in all cases like (+-5 lines): ------------ write(1, "Note: serprog_delay used, but th"..., 67Note: serprog_delay used, but the programmer doesn't support delay ) = 67 write(3, "\23", 1) = 1 write(3, "\1\0\0\2\0\0\5", 7) = 7 read(3, "\6", 1) = 1 read(3, "\0\0", 2) = 2 mmap2(NULL, 4198400, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7104000 write(1, "Reading flash...
