final flash offset of bootloader set to 200k right now bootloader code occupied 156k of flash so there is a small space left for future modifications

INSTALL PICO SDK
sudo apt update && sudo apt install -y cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential git
mkdir -p ~/pico && cd ~/pico
git clone https://github.com/raspberrypi/pico-sdk.git
cd pico-sdk
git checkout tags/2.1.1 -b sdk2.1.1
git submodule update --init
echo 'export PICO_SDK_PATH=~/pico/pico-sdk' >> ~/.bashrc
source ~/.bashrc
SETUP PICOCALC FIRMWARE
mkdir -p ~/picocalc && cd ~/picocalc
git clone https://github.com/madcock/PicoMiteAllVersions.git
cd PicoMiteAllVersions
mv ~/pico/pico-sdk/src/rp2_common/hardware_flash/flash.c ~/pico/pico-sdk/src/rp2_common/hardware_flash/flash.bak
ln -s ~/picocalc/PicoMiteAllVersions/flash.c ~/pico/pico-sdk/src/rp2_common/hardware_flash/flash.c
mv ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.c ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.bak
ln -s ~/picocalc/PicoMiteAllVersions/gpio.c ~/pico/pico-sdk/src/rp2_common/hardware_gpio/gpio.c
EDIT ~/picocalc/PicoMiteAllVersions/CMakeLists.txt TO CHOOSE TARGET
set(PICOCALC true)
# Compile for PICO 1 Board
#set(COMPILE PICO)
# Compile for PICO 2 Board
#set(COMPILE PICORP2350)
set(COMPILE WEBRP2350)
BUILD PICOCALC FIRMWARE
cd ~/picocalc/PicoMiteAllVersions
mkdir build
cd build
cmake ..
make
(original readme follows...)
PicoMiteRP2350
This contains files to build MMbasic V6.00.02RC23 to run on both RP2040 and RP2350
Compile with GCC 13.3.1 arm-none-eabi
Build with sdk V2.1.1 but replace gpio.c and flash.c with the ones included here
Change CMakeLists.txt line 4 to determine which variant to build
RP2040
set(COMPILE PICO)
set(COMPILE VGA)
set(COMPILE PICOUSB)
set(COMPILE VGAUSB)
set(COMPILE WEB)
RP2350
set(COMPILE PICORP2350)
set(COMPILE VGARP2350)
set(COMPILE PICOUSBRP2350)
set(COMPILE VGAUSBRP2350)
set(COMPILE HDMI)
set(COMPILE HDMIUSB)
set(COMPILE WEBRP2350)
Any of the RP2350 variants or the RP2040 variants can be built by simply changing the set(COMPILE aaaa)
However, to swap between a rp2040 build and a rp2350 build (or visa versa) needs a different build directory.
The process for doing this is as follows:
Close VSCode
Rename the current build directory - e.g. build -> buildrp2040
Rename the inactive build directory - e.g. buildrp2350 -> build
edit CMakeLists.txt to choose a setting for the other chip and save it - e.g. set(COMPILE PICO) -> set(COMPILE PICORP2350)
Restart VSCode
