[coreboot] Failed flash, flashrom emergency help needed on ICH7
I tried the latest svn version (6 May 09) of flashrom and unlike older versions didn't get a warning on my chipset. flashrom reads my chip successfully and outputs a fine Phoenix bios. After writing a new image into the chip I found that writer is not fully functional and reading the chip again results in an image that is neither original one nor the new image. then I tried erase functionality and it resulted in some 0xFF and some unchanged bytes in the chip. Currently writing either images doesn't change the chip and it remains in mostly 0xFF bytes. Here are the flashrom detection info : a...@velocity:~/tmp/f$ sudo ./flashrom/flashrom Calibrating delay loop... OK. No coreboot table found. Found chipset Intel ICH7M, enabling flash write... OK. Found chip SST SST25VF080B (1024 KB) at physical address 0xfff0. No operations were specified. verbose output at http://coreboot.pastebin.com/m604f01b6 history of my commands : http://coreboot.pastebin.com/m5c3c2372 Original Rom : http://filebin.ca/mhtqhm/mybios.rom lspci -vv output attached. I try to keep my Lenovo 3000 up and running and waiting for helps. :) I'm also online on #coreboot as nadalizadeh Thanks Ali Nadalizadeh 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) Subsystem: Lenovo Device 2082 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast TAbort- TAbort- MAbort+ SERR- PERR- INTx- Latency: 0 Capabilities: access denied Kernel driver in use: agpgart-intel Kernel modules: intel-agp 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) Subsystem: Lenovo Device 2083 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 16 Region 0: Memory at d810 (32-bit, non-prefetchable) [size=512K] Region 1: I/O ports at 1800 [size=8] Region 2: Memory at c000 (32-bit, prefetchable) [size=256M] Region 3: Memory at d820 (32-bit, non-prefetchable) [size=256K] Capabilities: access denied Kernel modules: intelfb 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) Subsystem: Lenovo Device 2083 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0 Region 0: Memory at d818 (32-bit, non-prefetchable) [size=512K] Capabilities: access denied 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Lenovo Device 2085 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: Memory at d824 (64-bit, non-prefetchable) [size=16K] Capabilities: access denied Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 02) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Bus: primary=00, secondary=02, subordinate=03, sec-latency=0 I/O behind bridge: 2000-2fff Memory behind bridge: d400-d5ff Prefetchable memory behind bridge: d000-d1ff Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast TAbort- TAbort- MAbort+ SERR- PERR- BridgeCtl: Parity- SERR- NoISA+ VGA- MAbort- Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: access denied Kernel driver in use: pcieport-driver Kernel modules: shpchp 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 02) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Bus: primary=00, secondary=04, subordinate=05, sec-latency=0

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hmm I checked the orig bios image for any special handling and there is none. Even it seems that EC has its own flash somewhere else. (this is good) Perhaps there are some locks in chip itself? Any expert here on that? Can we read the status reg from the chip? The WP# of the chip seems just to enable/disable modifications to the to the BP bits. I suspect the part flashing does not work well. There seems to be no obstacles elsewhere.

Re: [coreboot] Failed flash, flashrom emergency help needed on ICH7
Ali Nadalizadeh wrote: I'm also online on #coreboot as nadalizadeh Some analysis after Ali worked with Carl-Daniel and me to debug this. The chip needs a write enable command to set it's write enable latch before each erase or write command. flashrom sends this as a separate command, but for software sequenced ICH SPI that doesn't work, it needs to go into the ICH PREOP register and not be sent as an individual command. Because this fails when trying to send an erase command, chip erase aborts. Ignoring that write enable error allows the erase to continue, and succeed. This chip doesn't support writes of more than one byte at a time using the 02 command, but the flashrom ICH SPI driver (and maybe others) assumes that all chips support more data in one go. Many do. Ali had to go, and we have to rest a little, right now the machine is running AAI programming, writing two bytes at a time. If that doesn't work either, the next step is to try the 02 byte program command but actually send only a single byte at a time. (force maxdata=1 somewhere suitable) More updates this afternoon. I think it'll work in the end. //Peter -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
