PCI devices: IRQ table and vendor/device ID
by Andrea 29 May '08

29 May '08

Dear OFW developers, I'm going to a "new" PCI device on our custom (Geode LX based) board. I already add standard PCI support to our build (${BP}/dev/pcibus.fth), plus enabling some debugging stuff: true value pcimsg? true value probemsg? Is it possible to see its vendor/device ID from OFW? (we are going to create a custom OFW driver soon, but it will be enough to see it IDs for debugging purpose) AFAIK I also have to add "something" on PCI IRQ table to let the OS (in our case Linux) … [View More]

LPC Flash programming
by Andrea 29 May '08

29 May '08

Dear OFW developers, I've found that inside dev/geode/lpcflash.fth it seem there is the Forth code to program an LPC Flash. I try to use it (like on OLPC) but I have the following undefines: ./build neptune.rom --- ${BP}/cpu/x86/pc/neptune/devices.fth is newer than the target file fw.img --- Rebuilding fw.img --- Cmd: /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/Linux/x86forth /home/shared/devel/neptune/sw/ofw/openfirmware.git/cpu/x86/build/basefw.dic ../fw.bth ${BP}/dev/… [View More]
