The rpi-imager net installer that kerry_s refers to is built into the EEPROM bootloader (or at least the means to download it are) - just hold down the Shift key on a USB keyboard when you power it on.

Does not seem to be a second stage bootloader. The BCM2712 uses the EEPROM to bring up the RP1 via the PCIe interface. That means baremetal will need PCIe code to talk to the RP1 and everything on it? Not sure how much of the ISP code is also ...

If you want to upload Python code, '.py' or '.mpy' files, over the air that should be possible. The Pico W can fetch or be told to accept such a file which it can write to the file system and then be instructed to use that uploaded code. I have no experience of doing that nor do I know how to with B...

Hi, I'm looking for a way to update firmware through Bluetooth (Over The Air) with a Raspberry Pi Pico W, but I've found nothing on the internet about how to do this and if it's possible. My goal is to update this firmware with a mobile app on iOS and Android (thanks to Flutter). I've made the conne...

If it makes a difference, my CM4 has EEMC not SD card.

The current bootloader version is dated

Code: Select all

 2023/01/11 17:40:52, version 8ba17717fbcedd4c3b6d4bce7e50c7af4155cba9 (release)

Would updating to latest version allow me to access DISABLE_HDMI?
