I am now searching for a while a solution for my 3 prefered arduino nanos (ble, iot and rp2040) to do sdu (secure digital update = update sketch on micro from a sd card).
I found, that for samd micros simply #include <SDU.h> should be enough. Realy cool solution.
But unfortunately, at compiling with board Nano 33 iot which is a samd micro, the error "board not supported" is shown.
And for the other two micros with mbed os, i couldnt find a library/solution.

I had a look to the github link you sent. I am not really familiar with github, but it looks like, that the solution winner10920 developed is still open to be included into the library. Is this right?
And for the other boards, especially the RP2040 connect really no one has a solution?
I thought that SDU is an important thing... Isn't it?
Important to whom? You do not seem to be sure. It seems interesting for some that have developed some code you can use but that is different than important e.g., you would be willing to pay a couple of developers to implement this for your product because it would make you rich selling some product that needs this feature.
If it is important to you and you got the solution for another Arduino, you can use that one for your project that needs it. Use the RP2040 for another project or remove it from your list of preferred Arduinos. I feel you might not like that but sometimes you have to make hard choices.
