picotool VS hyperhdr-ha

You can also use Picotool to pull the firmware from flash, but that's slightly more involved.

- On windows you can download a prebuild version, follow the instructions on this link: http://purdea.ro/picotool/ - On other OSes follow the instructions here on how to build: https://github.com/raspberrypi/picotool

You may want to first save a copy of the original closed firmware, so you can go back to it in case you don't like QMK or VIAL-QMK. For that you will need to build picotool: https://github.com/raspberrypi/picotool And you will need to run something like the following to save the original firmware: sudo ./picotool save -a all.uf2 -t uf2

Yes! The picotool can do it. https://github.com/raspberrypi/picotool

I need to boot rp2040 from ram (no flash), which I have tested with the picotool (with USB) and picoprobe (with swd+gdb load) and I can boot from ram and flashing a LED.

git clone https://github.com/raspberrypi/picotool.git cd picotool mkdir build cd build cmake .. make

You can use picotool to save a copy of the entire flash as a uf2 file.

Perhaps someone has already figured it out: https://github.com/raspberrypi/picotool/issues/32

You can use https://github.com/raspberrypi/picotool to dump the flash.

Would the HyperHDR ambient light project work with a modern day OLED TV like the Sony A80J, which has built-in casting and native apps like Netflix etc?

I haven't gotten around to setting up Home Assistant yet, that's the next project on my to-do.. This should work but I haven't tried it yet! https://github.com/mjoshd/hyperhdr-ha
