Hello! I am currently working on firmware for LA104 (https://github.com/gabonator/LA104) which is device produced by the same company and uses the same processor. I took a bit different approach - simple operating system that can load ELF application images, so the development is much faster and also you do not need to think "which memory slot contains which app?" Just nice simple graphical application switcher solves this task:

So a lot of things will be reused from LA104 development. I do not have capacity to maintain this (DS203) firmware and I noticed that every week (or so) a new issue is reported. So I am hoping that new DS203/DS213 fw will be compatible with all hardware revisions and we will solve these hiccups with choosing the right firmware image for your oscilloscope - because there were multiple hardware revisions and you need to choose the right image version to get it working. Also people were puzzled to choose the right firmware, because there were 4 different ones which loads to 4 different slots. Not everyone understood the idea that you can load 4 different firmwares onto the device.... (just look into issues tab).

So I am now waiting for e-design to provide me with all source codes to start porting this (DS203) firmware to the new design.

Just out of curiosty, if anyone is reading this, give +1 if you also request the firmware for DS213, so I will know whether there is actually demand for it.

When I will start the development for DS213, I will let you know here

+1 for the DS213 for sure. I love this little thing but it needs some work.

Thank you, Marco Reps for pointing me to this.

+1 for DS213.

Thank you for working on this

[ImmortalRat]

+1, keep up the great work! amazing!

+1 for DS213 as well! Happy to test as well. I opened it up and found an SOIC-8 SPI flash chip, would a dump of that be useful?

When I originally got this, I thought it would be compatible with these existing FW's, as I thought only the analog input rate was increased. I've been so bummed, especially because it was like three times the cost of a DS203, or even a LA104, and the existing firmware has been so difficult to use that I haven't even used it successfully once...

@cmorche, that SPI chip contains the FAT filesystem you see when you attach your device to PC, so it holds only configuration and possibly screenshots and caputred signals. I am currently working on compatibility with DS213 and it works quite well, at least the operating system stuff, now I just need to figure out how to read captured data from FPGA and combine it with the fw I made for DS203. I will focus mainly on DS213, I cannot promise anything regarding the DS203, since it was made in various hw revisions and for me it is absolute magic what are the differences and I just dont want to spend much time with backward compatibility. Guys at e-design will be surely very happy, when owners of DS203 will upgrade to DS213 to try new features... :)

+1 for DS213.... I would be happy to help debug when you get an initial firmware. The current firmware is garbage and cannot trigger using single or normal trigger mode with high sample rates. It makes the product useless to me, so I really hoping you can fix and provide a new firmware quickly.

@gabonator I'm not sure if it's helpful, but I just noticed they released the source code for the latest FW update for the DSO213. Looking forward to any updates :)
