HP41 TULIP4041 update

[MeindertKuipers]

After receiving and testing the Pico2 boards I have concluded that some more testing is needed to verify if the new RP2350 CPU has enough advantages over the existing RP2040. The initial tests did prove that the Pico2 board behaves quite nice on the Development Board. For now the development of the TULIP4041 will continue with the RP2040 and the existing Pico1 board. Worst case the users need to switch to the Pico2 board later, which is not a big investment.
Today I have ordered the PCB's for the Development Board for the existing pre-orders. When I receive these I will verify them by assembling and testing one unit, and when I am happy with the results I will announce this.

The issues with the SD card I had with the Pico2 tests are resolved, it was due to an upgrade of the FatFS library, which dropped support for SDSC cards (<= 2 GByte), and I was testing with an older 2 GByte card. Only issue with the Pico2 is with one of the state machines, and this is still to be resolved. Most important wil be testing the power management of the Pico2.
