Application does not start after FSBL in Standalone SD boot

I have an application on a custom platform in SDSoC. I am able to build the application and bitstream, and when I load it on the SD card of my board and boot, I see the FSBL print a message over UART and my FPGA programming 'done' LEDs signal success. However, I don't see any output from my application. I have a print message at the very start so that I know if it begins, and I am not seeing it being displayed. Where should I look for the issue?

Re: Application does not start after FSBL in Standalone SD boot

Hi @christian.moncada,

You may want to connect System debugger in attach to running target mode, and check which code the processor is executing. Please see https://www.xilinx.com/html_docs/xilinx2018_3/SDK_Doc/SDK_tasks/sdk_t_tcf_attach_debug_linux_kernel_tcf.html?hl=attach%2Crunning%2Ctarget for an example

You may have to add both fsbl.elf and app.elf as symbol files, to get a proper source view
