Last year we got this notice as well, it was fixed with an update to mbed studio (1.4.4). We are seeing this again this year. 1. will there be an update to fix this? 2. why are we seeing this? If the license always expires it makes it hard to provide long term support for our products. The notice we are seeing is
[Warning] @0,0: L9931W: Your license for feature mbed_armcompiler will expire in 28 days
For regular usage the ARM Compiler 6 is not free to use and a licence have to be purchased. MbedStudio have an exception and in a combination of MbedStudio & AC6 it is possible free to use.
However the license needs to be renewed, that is usually done via updates.
GCC will be working anyway I think.
You can always use Keil Studio Cloud
You can setup your own settings in VS-Code
BTW KeilStudioCloud is much better than MbedStudio now.
After the update, bufferedserial stopped working. We are using a buffered serial rs485 port that was working before the update and now is not. We use pins PE8 and PE7 on our ST Micro 32 (STMH743VI6) at 115200 baud, 8, N, 1. The port was working just before the upgrade and stopped working just after. We do not see anything coming in or out.
