I'm having a hard time figuring out how to boot our kernel/filesystem on the ml300. I suspect it's a problem with the bootloader, but not 100% sure.
We're able to generate a file to program the FPGA with that will allow us to use the BDI2000 to boot the system. From trial and error, I've gotten the impression that the FPGA file includes a bootloader of some kind: when we didn't include some of the binary firmware with the FPGA file we couldn't even get the BDI2000 to boot the system. When we started including the binary firmware stuff (which I don't quite understand yet), the system came up to a state where we could boot with the BDI2000. So, based on that, I'm guessing that the systemace chip fills the bram with some sort of bootloader sometime around when it programs the FPGA. However, I haven't been able to build a FPGA file that would actually boot to a linux filesystem on the flash card. The FPGA programs, but then nothing happens (this is with the BDI2000 unplugged, I don't think any software can be run with the BDI2000 plugged in unless it's downloaded via the BDI2000, but I could very well be incorrect). I've looked at the Monta Vista partitions that came with the kit. I don't see any kind of stand alone boot loader, so I'm guessing that they have included their bootloader with the FPGA file. I don't know if this is a modification of the bootloading binaries that come with the Xilinx development kit. Could anyone clue me in? Thanks, ~lr ** Sent via the linuxppc-embedded mail list.
