Hi!
We're building a project for the nRF54 where we want to run an external library on the FLPR core.
Right now we have a prototype PCB with a module from Fanstel on it.
We have allocated enough RAM for the FLPR core to be able to load all the code for the library, and it compiles, but the issue right now is that once we flash the device it won't boot. Or at least we're not seeing any activity on UART. If we comment the library out of the build and leave the rest as is, then it acts as expected and we can read prints from main() over UART. We don't expect the library to interact with hardware or the OS before we initialize it in main, so this really has us stumped right now.
Any suggestions how we can debug this? Is there for example any way to get a log of what happens before we get to main() if we're not able to boot?
Any help appreciated, thanks!
