getting the pico usb host example compiled correctly
12/01/2022 at 19:51 • 2 comments

I couldn't find the picoprobe with openOCD until I flashed it with a pre compiled picoprobe.uf2 file instead of compiling it myself. If it works, it works - I guess.

found the related issue where I got the working picoprobe.uf2 got from: https://github.com/raspberrypi/openocd/issues/71
Basically pointing to this site where you can download the probe firmware:

https://www.raspberrypi.com/documentation/microcontrollers/raspberry-pi-pico.html#debugging-using-another-raspberry-pi-pico

So apparently there's a tinyusb bug that will break the usb hid example and throw something like this at you:
assertion "ep->active" failed: file "~/Projects/pico/pico-sdk/lib/tinyusb/src/portable/raspberrypi/rp2040/hcd_rp2040.c", line 164, function: hw_trans_complete

This has something to do with the debug mode and you need a flag to run cmake first before compiling:
```
PICO_SDK_PATH=~/Projects/pico/pico-sdk cmake .. -DCMAKE_BUILD_TYPE=Release
make -j8
```
I have yet to find out what the difference between -j8 and -j4 means but hey, that up their worked.

Building openOCD for picoprobe on M1 mac

12/01/2022 at 12:35 • 0 comments

Had some trouble compiling the openOCD version for the picoprobe on the M1 macbook. This is based on a thread on github and the official guides, plus some blog posts that basically copied from each other.

https://github.com/raspberrypi/openocd/issues/7

#install additional brew libraries
brew install libtool automake texinfo wget gcc pkg-config libusb

# some path magic so compilers know where to look for stuff 
export PATH="$(brew --prefix)/opt/texinfo/bin:$PATH"

# download openocd files with picoprobe branch
git clone https://github.com/raspberrypi/openocd.git \
  --branch picoprobe --depth=1

cd openocd
./bootstrap

# this enables the picoprobe and deactivates other modules that fail to compile otherwise
CAPSTONE_CFLAGS="-I$(brew --prefix)/include" \                      
  ./configure --prefix="$(brew --prefix)"  \
  --enable-picoprobe --disable-presto --disable-werror --disable-openjtag

make -j4

# this will probably overwrite your current installation
# and will break openjtag
make install

# optionally remove the installation folder
cd ~/git
rm -rf openocd

burning firmware onto an ST-Link to burn firmware onto anything else

at least I'm trying to find that out. The clones from aliexpress are supposed to be only able to program st chips. But I want to use it to program some SAMD-21 chips. Never done that as well. So this is a link drop first. Figuring it out for MAC OS.

install open-OCD via homebrew

for unlocking the stm for new firmware go here

https://hackaday.io/project/162597-st-link-clone-repurposing/log/156668-programming

install new firmware called cmsis-dap

https://mvdlande.wordpress.com/2015/10/05/cmsis-dap-on-a-cheap-st-link-v2-mini-adapter/

get this file

https://raw.githubusercontent.com/x893/CMSIS-DAP/master/Firmware/STM32/hex/CMSIS-DAP-STLINK21.hex

install with this line
```
openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "init" -c "halt" \

    -c "flash write_image ./CMSIS-DAP-STLINK21.hex" -c "shutdown"
```
doing this to flash arturos latest keyboard firmware, had to install arm gcc first. Brew doesn't work as it's not trusted. Downloading here helped.

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads
to compile arturos fine firmware, you need to add the ARM stuff to your path, otherwise you compile and wonder why he wont find "gcc-arm-none-eabi" again.
```
export PATH="$PATH:/Applications/ARM/bin/"
```

Hey Dave ;-) Thanks for #Five Cubed dude, much appreciated.

Man was that tough not copying your #Skeleton Attiny85 Handheld , I had to breakout the old copper tape. ;-D

Are you sure? yes | no

davedarko wrote 12/14/2018 at 10:32

it's weird, some people on twitter came with analog heroes who used the technic, others said I'm copying someone else who wasn't the first one to do it :D I feel weird that people applaud me while attiny85 + OLED handhelds aren't new... just do what you want to do, don't get distracted by the noise like I was the last 3-4 days :D

Good luck with the contest and may the force be with you. It's almost Christmas, so I'm in a Star Wars mood.
