Hey! I have found the solution for my problem! There was no problem with my computer or my ports, it was all my OpenRB-150 board, the issue was that one code was too much for it.
To solve it I did a reboot of the OpenRB-150 to enter the bootloader mode:
After that the board was again recognized by my computer and everything worked perfectly, I even uploaded sketch when it was in bootloader mode. After 30 seconds or so the board enter normal mode and I could upload new sketches like before. After trying some example codes, I tried the same code I was uploading when the issue started and, surprise, the board was again not recognized by my computer. I did the same process as before and put the OpenRB-150 into bootloader mode again. I changed one variable of my code and everything worked so I can pinpoint the issue:
That arraySize is too big for my code and breaks everything, but for example putting a 1000 works well. So it was a RAM/memory problem. Do you know if there Is any way to know the free space of RAM or memory after uploading a sketch, like happens in Arduino after uploading a code?
On the other hand, I got myself a better cable in case that could give me future problems. Is this cable good to do aplications with OpenRB-150?
Thank you for your help!
