Instead of a custom FSBL, create a fresh FSBL project using the Xilinx generic template. If the generic FSBL boots successfully, the issue lies in your custom modifications to the boot loader.
The top utility in this context serves as a real-time monitor for system resources, much like the standard Linux top command, but tailored for a specific binary environment ( c31bootbin ).
Boot failed: c31bootbin top > 0x20000
The initial stack pointer (read from address 0x0) points above c31bootbin top . Fix: Edit the bootbin header using a hex editor. Change the first 4 bytes to a valid SRAM top address (e.g., 0x0000F000 for 60KB SRAM). Recalculate any CRC.
Ensure the config.sys or equivalent initialization file points directly to the Top-level binary.
