This is for the mahogany_fam10 I just sent. It is not a signed-off-by patch. We need to work it out about this problem.

Porting to Asus M4A785-M
by Juhana Helovuo Aug. 26, 2010

Aug. 26, 2010

Hello, I am trying to get coreboot working on Asus M4A785-M with Athlon II X2 240e CPU (Socket AM3). So far there is no success. The mainboard is based on AMD785G + SB710 chipset, which has integrated ATI VGA. http://www.asus.com/product.aspx?P_ID=ef0qgvMIwOUagAVl&templete=2 The super IO chip is labeled ITE IT8712F-S. Please see the listings at the end of this post for details. There is only pin header connector for COM1 serial port on the mainboard. The back panel DB9 connector with cable to attach to the mainboard must be bought separately. (The one I got has too short cable to reach the PCI slot openings. And it was supposed to be an original Asus part!) The BIOS ROM is Macronix MX25L8005PC-15G, 1 MByte, DIP-8, mounted in a socket. Flashrom 0.9.1 recognizes the chip and is able to read and write it. I have built a small circuit board where I have two BIOS chips and can select between them with a switch. The board is sitting in the BIOS socket. This makes it easier to recover after flashing something non-bootable. I have tried with coreboot revision 5631 from SVN. First, I connected the board via a null-modem cable to another Linux machine, started getty at ttyS0, 115200 bps at the target machine and minicom at the other machine. I get login prompt and can log in via ttyS0, so the serial connection works. Then I tried to build coreboot for ASRock 939A785GMH/128M, since it is based on the same chip set. Flashing succeeds, but booting does not work. Power light comes on, fans start, but otherwise there is no sign of life, nothing on the serial port. Then I noticed that the super IO type is different, make a new directory under src/mainboard/asus for this board type, copy the contents from the ASRock board, and change the references to the super I/O from a Winbond chip to the ITE IT8712F. There seemed to be a some code in the romstage.c that toggled the GPIO pins in the super I/O chip, in function sio_init(). I made a guess that this was something specific to the Winbond chip, so I commented those out. The guess was based on #define -lines after the #include -section. Also I generated a new irq_tables.c with the utility provided with coreboot sources. Now, when attempting to boot, I get the following from the serial port: coreboot-4.0-r5631M Mon Jun 14 04:56:01 EEST 2010 starting... bsp_apicid=0x0 Enabling routing table for node 00 done. Enabling SMP settings coreboot-4.0-r5631M Mon Jun 14 04:56:01 EEST 2010 starting... bsp_apicid=0x0 Enabling routing table for node 00 done. Enabling SMP settings coreboot-4.0-r5631M Mon Jun 14 04:56:01 EEST 2010 starting... bsp_apicid=0x0 Enabling routing table for node 00 done. Enabling SMP settings [...the same repeats...] Now what to do next? The wiki documentation left me wondering what exactly are the necessary steps to port coreboot, provided that all the basic components are already supported. Which board-specific files are needed, and which ones can be auto-generated vs. manually coded?

[patch] DDR3 support of AMD Family 10
by Bao, Zheng Aug. 11, 2010

Aug. 11, 2010

DDR3 supporting is added. More testing need to be done. But we don't have boards that cover all the options. Features that have been tested. The socket AM3 and ASB2. Single rank and double rank DIMM. Features that need to be tested. Socket C32 and G34, I don't know if it is DDR3. Quad rank. Registered DIMM, which is quite complicated and I am not confident about. The tilapia board is the demo that shows the way to use DDR3. It is quite close to mahogany, except tilapia uses AM3. For a new board, just specify the socket type in Kconfig the devicetree.cb.

compiling coreboot
by ali hagigat Aug. 9, 2010

Aug. 9, 2010

If i execute only this command at the root folder of Coreboot source tree : make Will the project be compiled with GCC of the system or GCC of the system will be patched and changed or it will be compiled exactly with regular GCC of the linux operating system? Besides will be the object files in elf format and when they are linked? Is there any possibility for other formats?

ASUS M4A77TD-PRO. First step: buy spare flash chips...
by xdrudis Aug. 3, 2010

Aug. 3, 2010

Hello. I finally bought the hardware I told you and installed gnewsense 3 with a custom linux-libre 2.6.34 : mainboard Asus M4A77TD-PRO http://www.asus.com/product.aspx?P_ID=0AvsBb7WBZe2i9zK CPU AMD Phenom X4 910e stepping c3 AMD 770 AMD SB710 RAM 2 x 4Gb dual channel non-ECC G.Skill DDR3-1333 PC3 10666 F3-10666CL9D-8GBRL superio ITE IT8712F (clearly marked on the chip and detected) lan: RTL8112L audio VIA VT1708S I've put a graphics card by MSI, Nvidia GeForce 8400GS passively cooled (no fan) on the PCIExpress 2.0 slot. I'll attachs the lspci and superiotool r3125 outputs (versions from gNewSense) and flashrom 0.9.2 downloaded and compiled from release tarball. Btw. The readme in flashrom 0.9.2 says to use make DESTDIR=/usr install if you don't want it in /usr/local, but this will install it in /usr/usr/local/sbin. To have it in /usr/sbin you need to run makePREFIX=/usr install. It's slightly confusing for me, I've had to look at the Makefile. Now, the first thing I want to do is to buy spare flash chips. But I'm not sure what chips or where to buy them. It's a socket with an eight pin chip (DIP-8?) (4 pins per side), roughly 5mm x 9mm I'd say it's by Macronix (and flashrom agrees). But I doubt about the specific model. The motherboard manual says "8Mb Flash ROM". The letters on the chip are very small and there's some marking over them that keeps me from reading them all . I'll copy here what I can read (i mark the most dubious letters with ?). (top left is a logo MX) - - - - -- -- - - = v = = = b09?714 = = = = 25L5???5PC-15G 3C153600 TAIWAN Looking at catalogues from macronix I think 25L is the family (SPI serial flash) 5?? should be the size (I'm not sure how many digits are there, not even 100% sure it's a 5) ?5 would be normal, write protected, duplex,etc. PC might be the process ( xx micrometers), -15 would be frequency of 66 Mhz and G something about lead free or environmental regulations. but flashrom says its a Macronix MX25L8005 . http://www.macronix.com/QuickPlace/hq/PageLibrary4825740B00298A3B.nsf/h_Ind… Now, the question is should I buy some MX25L8005 ? (apparently its end of life is 2010-11-30, so it should be available, but where in small quantities ? ) According to http://www.macronix.com/QuickPlace/hq/PageLibrary4825740B00298A3B.nsf/h_Ind… maybe I could try Mx25L8006EPI-12G Where do you get your spare EEPROMs ? Thank you.

coreboot halts at "doing early_mtrr"
by austinro＠msu.edu Aug. 1, 2010

Aug. 1, 2010

Hi. I have a Jetway 7F4K1G5S-LF board I'm trying to get working. When I build coreboot using the J7f24 target, it doesn't get past "doing early_mtrr". I added a few print statements (and included console.h) to try to track it down, and in "include/cpu/x86/cache.h" in disable_cache it will print the statement before write_cr0(cr0); but not the one after it. I don't know what to try next. I'm doing this on a 32-bit sidux box, with gcc 4.4.4. Any ideas? Thanks, Rob Austin

What is the rule of the SPD address assignment if there are more that 8 dimm slots?
by Zheng Bao July 31, 2010

July 31, 2010

The board tht I am working on has 2 process. Each of them has 6 DIMM slots. If you plug 1 dimm into each slot, the SPD address will be, Channel PCB ---------------- P0: DIMMA0 50h DIMMA1 51h DIMMA2 52h DIMMB0 53h DIMMB1 54h DIMMB2 55h P1: DIMMA0 50h DIMMA1 51h DIMMA2 52h DIMMB0 53h DIMMB1 54h DIMMB2 55h If you plug 1 dimm in P0DIMMA0 and the other in P1DIMA0, the SPD address will be 50h and 55h. So I am confused. If we got an active spd 0x50 on the SMBUS, what will it be? It seems that we can not plug more that 8 dimm even if we have 12 slots, correct? Zheng
