TamaGo fails to initialize on Raspberry Pi 2 (v1.1) #4

Closed kenbell closed 4 years ago

kenbell commented 4 years ago

I've raised a PR to drop out of HYP mode (default on modern Pi firmware) against tamago-go: https://github.com/f-secure-foundry/tamago-go/pull/1

With this, and some basic board support for Pi2 I'm able to get a hello world / blinky lights app working.

Thanks, we'll take a look! Any chance of getting the other tamago patches to get Pi2 support published? We would love to integrate those as well.

kenbell commented 4 years ago

Absolutely - working on tidying them up. Will raise a PR.

@abarisani - thanks for merging the HYP mode change. I've got a couple more PRs to add support for Pi 2B and Pi Zero - one for tamago-go and one for tamago itself: https://github.com/f-secure-foundry/tamago-go/pull/2 https://github.com/f-secure-foundry/tamago/pull/5

Combined these support UART, Watchdog, on-board LEDs.

I've also got a couple examples - one for each board: https://github.com/kenbell/tamago-example-pizero https://github.com/kenbell/tamago-example-pi2

If you're interested in hosting this code in this project, let me know - happy to contribute them.
