Softserial support for Sparky 2.0 .. iNav 2.6.1

[jerrynsr]

Hi,
Has anyone been successful with configuring softserial on the Sparky 2.0 STM32F4 flight controller ? I have plenty of resources available and need two 57600 TX ports to complete my AR mini wing build. The softserial ports are needed for Frsky telemetry and FC output to the minimodOSD.
I'm using the LED 6 pin port to control aviation lights and a status light. I wanted to configure telemetry and OSD before I install my rf shield that goes on top of the Sparky controller and ESC. The BN-220 mounts on top of it in a 3d printed cage. The shielding helps achieve really good performance with the BN-220 GPS. 3D Lock with 18 satellites.

The resource serial_tx command appears to fail and resource only echoes back the current mapping, I can not remap anything even if the resource is free. Is there a step I am missing here to remap resource A00 ? The resource is free and according to the Sparky 2.0 schematic it maps to pin servo out 6.

Any help would be appreciated. Thanks!

I've been searching the web for some programming clues and I found Pawel's extremely informative video on YouTube regarding resource mapping for STM32F4 targets. I agree there are some people not familiar with the architecture and if they mapped resources with the inav configurator and not familiar with the architecture they will run into trouble. My requirements are simple. I have several flying wings where I'd like to use servo out 5 & 6 for softserial TX at 57600. This is not a problem. I will add these features and post it to the inav 2.6.1 repo as soon as I test it out. I'll also add a link to the ar mini wing and the ar wing pro that I am building. I found a source to the Sparky 2.0 TauLabs hardware, with connectors, case, and cables.. complete kit for $25.00 USD. Awesome deal when Pixhawks and Matek hardware are getting expensive. Plus the Sparky/Revo controllers are small and can be fit in small airplanes, or larger airplanes where you want to carry a larger flight battery. I am starting with 2.6.1 because the iNav 2.6.0 Sparky 2.0 firmware is still in Beta and not all functions are available. I'll keep you posted.
