[LinuxBIOS] resourcemap for IWill dk8htx
by Philipp Degler 22 Mar '06

22 Mar '06

Hi I started porting LinuxBIOS to IWill dk8-htx board. I used the dk8s2 to start from. After some smaller changes to the Config.lb I could compile it and flash it with flashrom. Unfortunately it seems that the default_resource_map is not working. This is what I get when I debug a little. LinuxBIOS-1.1.8_Fallback Wed Mar 22 16:32:37 CET 2006 starting... i386 console_init report_bist_failure setup_default_resource_map setting up resource map.... 0000c14c <-00000001 0000c154 <-00000002 0000c15c <-00000003 0000c164 <-00000004 0000c16c <-00000005 0000c174 <-00000006 0000c17c <-00000007 0000c140 <-00000000 0000c148 <-00000000 0000c150 <-00000000 0000c158 <-00000000 0000c160 <-00000000 0000c168 <-00000000 0000c170 <-00000000 0000c178 <-00000000 0000c184 <-00000000 0000c18c <-00000000 0000c194 <-00000000 0000c19c <-00000000 0000c1a4 <-00000000 0000c1ac <-00000000 0000c1b4 <-00000000 0000c1bc <-00ffff00 0000c180 <-00000000 0000c188 <-00000000 0000c190 <-00000000 0000c198 <-00000000 0000c1a0 <-00000000 0000c1a8 <-00000000 0000c1b0 <-00000000 0000c1b8 <-00fc0003 0000c1c4 <-01fff000 0000c1cc <-00000000 0000c1d4 <- Is there any documentation or specification that can help me setting up this resourcemap? phil

[LinuxBIOS] Firmware hub parts
by Richard Smith 21 Mar '06

21 Mar '06

I got my eval board today. The bios chip is a sst 49LF002A which is a firmware hub part. My ROM emulator won't work. :( My programmer will program the parts but that means I'm swapping chips every cycle which sucks. Do all the GX2 parts use firmware hubs? What are my non-programmer options for flashing this part? -- Richard A. Smith

2 years ago I lucked out and picked up a copy of MSVC 1.52 on ebay for a couple of bucks. It might be worth checking ebay.

ok, gx2 bios for lippert will now call vsm, and then ... lockup. for those of you who want to experiment with this ... we're waiting on our jtag debugger. ron

[LinuxBIOS] flashrom utility
by Stefan Reinauer 15 Mar '06

15 Mar '06

Hi, I would like to reduce the address output during flashing, verifying etc in the flashrom utility. Instead of printing each address, it would be sufficient to write every 256th address or even every 4096th address: so we could write if (verbose && ((i&0xfff)==0)) printf("0x%08x", i); instead of if (verbose) printf("0x%08x", i); The reason is if you are writing/verifying flash on a reasonably slow serial console it will take several hours (and hopefully not mess with the flash timing) any vetos?

Re: [LinuxBIOS] [olpc-software] How fast does it take to write a system from a scratch?
by Jim Gettys 15 Mar '06

15 Mar '06

Nope. News to me of its existence. Have any idea of the ub driver's size? The trick is to get at least restore from USB storage able to be in the boot flash; I don't mind so much if we have to put TCP/IP and wireless modules into a partition on the regular flash. And if we can get it all to fit into less than 512K bytes (BIOS + Linux as bootloader), then we get to save $.3 to $.5, which over the number of units we're building, is more than small change.

[LinuxBIOS] Lippert Cool Roadrunner 2 (GX1)
by Per Dalgas Jakobsen 14 Mar '06

14 Mar '06

Hi all, At last... Finally I have had time to look at LinuxBIOS... I have been playing around with Etherboot and Filo for booting a development target, making good progress. Up to now I have managed to add Etherboot to the original BIOS and have it working fine. But now I want to LinuxBIOS my system ;-) I have a Lippert Cool Roadrunner II with 64MB memory and a 128MB CompactFlash for disk, and I have tried to use LinuxBIOS v1 with its support for this board, but no success. The serial port is very quite, and unfortunately I have no POST card. I have verified the serial connection: Linux on target "$ echo Hello >/dev/ttyS0" gives a nice "Hello" on the receiving end (no handshakes), so something seems odd with the LinuxBIOS image... Host is i686-Linux using gcc-4.0.3 --- config ------------ target /home/pdj/tuxway/builds/roadrunner2 mainboard lippert/roadrunner2 # Enable Serial Console for debugging option SERIAL_CONSOLE=1 option TTYS0_BAUD=57600 option DEFAULT_CONSOLE_LOGLEVEL=9 option DEBUG=1 option RAMTEST=1 option USE_GENERIC_ROM=1 option USE_ELF_BOOT=1 option ROM_SIZE=262144 option STD_FLASH=1 payload ~/tuxway/etherboot-5.0.6/src/bin32/eepro100.elf option PAYLOAD_SIZE=196608 --------------- I've hexdump'd the resulting romimage, and it looks fine as far as I can tell: (jmp far 0xf000:0x0004 at address 0x0003fff0, and payload image starting at 0x00000000). I've used the flashrom from LinuxBIOSv2-2191 for burning: "# flashrom -w romimage" Anyone able to give me a clue of what I've missed? Anyone had success with LinuxBIOSv2 on a Roadrunner2 ? ~Per ----------------- PS: --- My ultimate goal is fast boot to either a remote image (through Etherboot) or a local linux on CompactFlash (filo and ext2). My plan was to use LinuxBIOS with a combined filo and etherboot image as payload. Like this: 0x000000 FILO 0x010000 ETHERBOOT 0x030000 LINUXBIOS 0x040000 --- I have already modified filo so an external switch can select the boot-method.
