-Getting bare metal code running on tricore
-Description of problem:
-My code is stuck in
-Steps to reproduce:
-1. Open Infineon Aurix Development Studio (on Windows)
-2. Compile project (two examples that I've tested)
-a) New -> Project -> Board -> KIT_AURIX_TC277_TFT_DC-Step -> Build
-b) the example from here: https://github.com/Infineon/AURIX_code_examples/tree/master/code_examples/Blinky_LED_1_KIT_TC277_TFT
-3. Copy the elf and run qemu on the debian system
-Additional information:
-When running a blank binary on QEMU with the TriCore TC27x target, the CPU starts executing at address 0x80000020 and enters an infinite loop.
-The code seems to be stuck and waiting for some hardware signal. The binary (sample.elf) from this issue qemu-project/qemu#1363 works. 
-
-I know it's probably a rookie problem, but what am I missing? How can I get an example from Infineon running? Or any other example?
-
-Please let me know if you need additional information!
