Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

V6.03.00 is now available at https://github.com/UKTailwind/PicoMite/releases/tag/PicoMite-V6.03.00
The user manual, gui manual and all other ancillary documentation is available at https://github.com/UKTailwind/PicoMite/tree/main/docs
Various python scripts for use by users are on https://github.com/UKTailwind/PicoMite/tree/main/user-tools
The latest version of the CFunction header is here

In the next days I'll get all this packaged up for Geoff to include on his site and will post release notes on this thread.

As far as I'm aware the release picks up the various comments on the RC thread and the documentation thread (where I agree with them ).

For info, the github is now completely re-organised. If you want to build the PicoMite firmware for yourself and assuming you have the compiler and pico sdk loaded and set up then all you need to do is as follows:

Create a new directory and cd to that directory
git clone https://github.com/UKTailwind/PicoMite.git
cd Picomite
buildpicomite [what]
'what' can be nothing (builds every version) rp2350, rp2040, or a specific build

Peter,
this version doesn't start up every time on my PicoCalc; it takes a long time to boot and then displays the following message:
Invalid clock speed - reset to default

In addition, you hear a "pop" through the speaker every time a launch is successful.
That wasn't the case with version PicoMiteRP2350V6.03.00RC26 - everything was fine back then...

Nuke the pico and try again. I've borrowed the PicoCalc again and it works perfectly for me. If you still have problems then we need to wait for any other PicoCalc users to report

I nuked it again ( universal_flash_nuke.uf2 ) and flashed it with PicoMiteRP2350V6.03.00.uf2.

No difference...

Do the following, if this doesn't work I'm beginning to suspect your PicoCalc is on the way out.

Load PicoMiteRP2350VGAV6.03.00.uf2

You should see it boot up as follows: then reload PicoMiteRP2350V6.03.00.uf2 and it should immediately re-confiure for the PicoCalc

On this PC, the terminal only works through the USB-C port. And that port isn't enabled by default yet.

Okay, I loaded universal_flash_nuke.uf2, then the USB version, and then the regular version.
I had to restart PicoCalc twice, then I saw the message "Formatting the A: drive," and when I entered "OPTION LIST", "OPTION PLATFORM PicoCalc" was displayed.
After a restart, the following message appeared again:
Invalid clock speed - reset to default

What's really striking is that it almost never starts up with an SD card inserted, but it works more often without one.
Sometimes the "Invalid clock speed" message doesn't appear either...

The console should work connected to the Pico irrespective of whether the PicoCalc is turned on or not

What OS is this for? It won't run in Ubuntu at all, it fails in PowerShell Admin mode with a permission error. It looks like a windows batch file but it won't run in Windows, either.

No idea of the hardware design but if the 3V3 output of the Pico itself is used I would check if the current is for some reason too high.

Edit: ..and if the Pico runs isolated with these cpu speeds.
Do you use a diffent SD card than before?

I’ve just updated the PicoCalc with a 2350 (also known as pico2) to version 6.03. It’s been running smoothly so far.

However, the "new" command alone sometimes results in a screen that isn’t displayed properly (the command simply appears twice at the bottom of the screen). But "cls" sorts it out.

  Quote  What OS is this for?

W11, run in a developer command prompt window. Get an AI to convert to linux, should be trivial, but first make sure you can execute cmake and nmake from the command prompt to build one of the Pico example programs

I tried Linux commands directly.

One problem was that I had to edit PicoMite/net/mbedtls_config.h to add

#include <stdio.h>


then I actually get the compile stage to 98% Now I get this:

Relocating gpio_default_irq_handler into RAM (.time_critical)
CMake Error at cmake/relocate_gpio_irq_to_ram.cmake:36 (message):
 relocate_gpio_irq_to_ram: no hardware_gpio/gpio.c.obj found under
 /home/tlake/PicoMite/CMakeFiles/PicoMite.dir


I'm stuck. Any ideas?

Yes, you're right about that! That's a problem with my stupid Linux PC. Knoppix doesn't have a driver for the Raspberry's serial port. That's why I can only access it through the USB-C port.

I think I'm going to toss that piece of crap PicoCalc in the trash soon!!!
