Deploying a nikola site to FTP

asmw — Sun, 07 Feb 2021 13:57:52 GMT

If you want to generate a static website using the Nikola but need to deploy to a hoster who only provides FTP you can use ncftp to automate the process.

Install ncftp. On Debian-based distributions apt install ncftp should work
Save you server credentials to a bookmark so they do no appear in your nikola config
- Log in to the FTP server: ncftp -u <username> ftp.ftp_server.com
- Create a bookmark: bookmark <bookmark name>
- Confirm whether you want to save your password or not
- Quit
Add a deploy configuration to you conf.py:

DEPLOY_COMMANDS = {
    'ftp': [
        "ncftpput -R <bookmark name> / output/*",
    ]
}

Run nikola deploy ftp

Bootloader fix for Makerdiary nRF52840 MDK USB dongle

asmw — Sun, 07 Feb 2021 11:37:11 GMT

Break the bootloader on an Makerdiary nRF52840 MDK USB Dongle
- You can do this by flashing an OpenSK build which was built around the first week in february 2021
Have a SWD capable JTAG interface
- I use a rather old Busblaster v2.5
- A Raspberry Pi Pico might be a cheap alternative, haven't tested this though
Have openocd installed
- apt install openocd for Ubuntu
Grab a fresh bootloader
- I used uf2_bootloader-0.2.13-44-gb2b4284-nosd.hex
Wire up the dongle based on the pin description
Note that I set the Busblaster to provide 3.3V

Create a openocd script, e.g. flash-bootloader.cfg (You will have to adapt this to your JTAG interface)

flash-bootloader.cfg (Source)

	`source /usr/share/openocd/scripts/interface/ftdi/dp_busblaster_kt-link.cfg`
	`transport select swd`
	`source /usr/share/openocd/scripts/target/nrf52.cfg`
	`program uf2_bootloader-0.2.13-44-gb2b4284-nosd.hex`
	`reset`
	`exit`

Run openocd: openocd -f flash-bootloader.cfg
- You might have to press the reset button on the USB dongle to get a connection

Let's try this again

I will try to upload posts to this blog regularly. Let's see how that works out.
