Booting in multiple ways

It’s been a little while since I last posted but a lot has happened. We have now successfully run u-boot in both UART boot and SPI boot modes. Tim Louden managed to quickly get together a flash driver for our spi chip that allows us to interface it with u-boot. Now the real work begins. The kernel itself. We found that the version of the toolchain that we were using was not compatible with the version of the kernel that we were using so we reverted back to the most recent release of the kernel rather than the svn version. This is currently being worked into the repository and hopefully linux hacking can begin tomorrow. Once we get the kernel booting the next big task is to see if we can get the audio codec to respond.

Move to BF537

Major Design Change! We moved to the BF537 part. It is compatible with all components of the curent design but adds features such as 802.3 MAC, CAN, TWI (I2C) along with more timers and GPIO. It will also make interfacing with the audio codec easier. My part generator cranked almost a second to spit out the 208 pin part, but it’s done and I am progressing on schematic capture.
