Pinouts

The pinout in the schematic is not correct. Instead it is:

GPIO	Function
6	M0_JTAG_TMS

12	M0_JTAG_TCLK
13	M0_JTAG_TDI

Creating an Apache NuttX Release

Checkout the distribution SVN repositories

Releases are managed through an SVN repository. There are two locations where releases can be committed dev and release. Prior to voting a release is staged in the dev folder after a release is approved by the IPMC it is then moved to the release location and committed for distribution. The release folder also holds the GPG public keys that are used for signing release in a KEYS file.

svn checkout https://dist.apache.org/repos/dist/dev/incubator/nuttx nuttx-dev
svn checkout https://dist.apache.org/repos/dist/release/incubator/nuttx nuttx-release

Adding your gpg key

Inside of the dist/release/incubator/nuttx folder is a KEYS file where committers must upload their GPG public key that they use to sign releases. On the top of the file you can see instructions on how to add your key to this file. Be careful to not remove any existing keys. There is a KEYS file in both the dev and releases folder, but uploading to the

Booting NuttX via Grub

Note: These instructions are somewhat Fedora specific and also rely on my partion setup.

You will need to make sure on Fedora you have the grub2-efi-x64-modules package installed to provide the multiboot2 grub module.

1. Create a new file /etc/grub.d/20_nuttx:

#!/usr/bin/sh
exec tail -n +3 $0
