Nice Spectrum Analyser... but does it run DOOM?


There's been quite some talk about the excellent Siglent SS 3021X Spectrum Analyser. It's a great piece of entry-level hardware, especially for the pricepoint.
See:
https://www.siglent.eu/siglent-ssa3021x-spectrum-analyser.html
and:
EEVblog's review/comparison:

It's also quite hackable:

You can login over telnet using: root/ding1234 as login/password.

'dmesg', 'cat /proc/cpuinfo' and friends tell a lot about this device.
It seems it's based on an am335x chipset from TI.

The framebuffer is accesible throught /dev/fb0

Mmm.. let's run DOOM on this thing!

Fetch the same toolchain Siglent used to compile software for this spectrum analyser:
https://releases.linaro.org/archive/13.03/components/toolchain/binaries/

Compile my minimal DOOM fork:
$ git clone https://github.com/maximevince/fbDOOM
$ cd fbDOOM/fbdoom
$ make CROSS_COMPILE=arm-linux-gnueabi-hf-

Copy fbdoom over to the Siglent (e.g. using USB stick, or busybox wget, first crosscompile dropbear, ...)

Play!
Only auto-playing demo for now, I haven't actually implemented any of the input controls (no keyboard or mouse)

The excellent JTAGenum for Arduino

As I said before, I've been fiddling with finding the JTAG port on a Verbatim PowerBay NAS. I did not succeed (yet), but have had the chance to try out JTAGenum for Arduino. It is an excellent JTAG pin finder (and other things too). Check it out here: http://deadhacker.com/2010/02/03/jtag-enumeration/ The guy's description of the tool is: 1. Given a large set of pins on a device determine which are JTAG lines 2. Enumerate the Instruction Register to find undocumented functionality 3. be easy to build and apply It's really easy to use, but it did not manage to find the JTAG pins on my device. There might be another problem, such as: - JTAG is disabled once the device is powered up - The pins I'm fiddling with are not JTAG pins - I ruined the circuitry already - I'm just not trying hard enough Back to JTAGenum: Since Arduino IDE 1.0.1 , some things have changed and so the GIT version of JTAGenum would not compile as-is. Therefor the JTAGenum sketch had ...

[RPi4][ Using the PiMoroni Fan Shim on LibreElec including the LEDs!

I recently bought a brand new Raspberry Pi 4, and wanted to try Kodi on it. There is only one Kodi-distribution which has more or less decent support for RPi 4 at the moment, and that's LibreElec (although still Alpha). Since the RPi 4 is famously overheating and throttling without a fan or at least a heatsink, I got a PiMoroni Fan Shim. Nice piece of hardware, but their library cannot run on LibreElec, because they do not support installing python libraries through pip etc... On LibreElec, the whole rootfs is a read-only squashfs image. So there's no way you can install the Pimoroni python library on LibreElec, but I found an alternative: I found Phil Randal's blog at  http://www.philrandal.co.uk/blog/archives/2019/07/entry_214.html , where he described how to get at least the Fan portion of the Fan Shim working on LibreElec. I decided to build on that, and port the LED functionality to LibreElec as well, without the need for "pip install" or a...

Arch Linux: Fixing empty/blank windows for graphical applications that require root

When running applications such as "unetbootin" or "tuxboot", you might get a blank window, instead of the actual application. Even when running it through "gksudo", or having a decent polkit running (e.g. inside Gnome). E.g.: This is because these application use MIT_SHM (Shared memory), which for some reason does not work when running graphical applications as root, while being logged in as a regular user in X. The solution is to disable MIT_SHM. E.g.: $ sudo QT_X11_NO_MITSHM=1 tuxboot
