[Help] Trouble running rust on xmc4500 relax lite kit

[SirWalross]

Hello,

i have trouble running rust on my xmc4500 relax lite kit. Here is my project: https://github.com/SirWalross/xmc4500-rust. I can compile the project with cargo build, but if i try to debug it with the JLinkGDBServer using cargo run it never reaches the main function.

If i step in gdb it just gives me some weird error messages: Internal error: pc 0xbc4 in read in CU, but not in symtab.

I would very much appreciate any help, tips or information what i am doing wrong. Thanks in advance.

using

• arm-none-eabi-gcc 13.2.0
• arm-none-eabi-gdb 13.2
• JLinkGDBServer V7.92o
• rustc 1.74.0

Ok, turns out the provided linker file doesn't work for some reason, with a custom memory.x file it works now.

But i have another question, how do you define an interrupt handler? For example the stm32f3 library exports a interrupt macro, but i couldn't find the counterpart for the xmc4500. Could you provide an example for defining one?

Thanks in advance.

Glad you were able to figure it out. I have sadly not been able to put the time in to these that I have wanted to so they are very incomplete. I am open to any PR that you want to contribute.

I myself have an XMC42xx kit and hope to attempt better work on these in the coming weeks.
