The next batch of PCBs have arrived. I spent an evening soldering and debugging the first prototype of Mackerel-10. I have only gotten as far as connecting the CPU, ROM, and RAM to the CPLD. The DUART is not working yet, but the 68010 is running C code that controls a memory-mapped LED register on the CPLD. No catastrophic design issues so far. Next step is to get the serial port working and modify some of the Mackerel-8 code to run on the new system. Without DRAM, I won't be able to run uClinux 4.4, but 2.0 should fit in the 1MB of onboard SRAM. I'd like to see that running on this hardware before I move ahead with a DRAM controller.

In other news, Revision 1.1 of Mackerel-08 has also been assembled and mostly tested. It boots to a monitor prompt and passed my RAM test for all 3.5MB. I need to make a few small modifications to the code to support the new SPI layout, but things are looking good. Once SPI is working and I can stress test uClinux, I think Mackerel-08 is approaching hardware completion. I can continue to work on the software/Linux side, but it will be nice having a solid baseline going forward.
