Hrm, I'm assuming `rotator` is a 64-bit barrel shifter? That would explain a lot :P.

@mikey It's worth a shot to me, tbh. I don't need the MMU or dcache either. This particular board only has enough LUTs to run Microwatt as a 64-bit microcontroller....

>Do you need external DRAM? Would be "nice to have" but certainly not a requirement for a microcontroller-only config. E.g. Micropython will work just fine using BRAM resources. Idk how...

To be 100% clear, I wanted Microwatt to fit into the 12/25F part :D!

The icache inference may have been a problem, but the core still didn't fit into OrangeCrab even when I essentially disabled the caches :P.

For anyone else who runs into this error, this fixed the issue for me: You need to recompile `ghdl` with the `--with-llvm-config` option. Example: ``` ../ghdl/configure --prefix=$PREFIX --enable-libghdl --with-llvm-config ```...

I've run into this with my [`migen_uart`](https://github.com/cr1901/migen_uart/blob/master/migen_uart.core) core: * I have a [design](https://github.com/cr1901/efbutils/blob/main/ufm_reader/ufm_reader.core), which uses an FPGA-internal clock. I.e. _clock speed is configurable at the command line_. * I want...

It looks fine to me (I think at the time, I only focused on bus-powered applications b/c I found it difficult to reliably put the [MSP-EXP430F5529LP](https://www.ti.com/tool/MSP-EXP430F5529LP) into self-powered mode. I...

Ack re: the errata; when I did this port originally, I don't recall looking at the errata. That's fine then (incl. your upcoming changes). > I'm using FreeRTOS for my...

@clhenry Just to be clear, @hathach may be very busy, and while I am a collaborator, I mostly focus on backend stuff. I want to wait for @hathach to be...
