picocart64-develop-20241031

New stable release that also contains a 133 MHz build.

The 133 MHz variant is not overclocking the RP2040, and the flash is read at 66.5 MHz. Low quality boards and flash chips should work better with this.

In the 133 MHz variant, the PI bus configuration is patched to run with a slower latency (0x80372040), and the SRAM emulation is also limited in speed, hence the SRAM test in the test ROM will fail (this is expected behavior).

Changelog:

• Uses ghcr.io/kbeckmann/pico-sdk-builder:ubuntu-24.04
  This also pins the GCC version to 13.x which is stable
• Adds 133 MHz variant (not overclocked, Flash runs at 133/2 MHz)
• Updates Makefile for the N64 testrom so it works with newer libdragon
• Disables SecondThread

This release is broken, do not use.

Snapshot of the unstable branch from 20240721.

This branch runs FreeRTOS and enables stdio over USB.

Also, there are 133 MHz builds. These builds are not overclocked and also run the external flash at 133/2 MHz which should be compatible with very cheap NOR-flashes found on low cost "pico clones".
