From 003d56c5489178adbd917fe579e3ea0a12498fe9 Mon Sep 17 00:00:00 2001 From: Padmarao Begari Date: Mon, 7 Apr 2025 19:15:44 +0530 Subject: [PATCH] configs: versal: Fix initial stack pointer The mini u-boot is getting exception because of an initial stack pointer address is used at near the top of memory, and while executing u-boot is assigned pre-malloc and global_data memory after initial stack pointer and updated the stack pointer. Serial driver is used pre-malloc area for serial operations before relocation. But pre-malloc area is cleared while doing BSS at relocation time. The u-boot is called board_init() function and doing printf, relocation serial driver is not initialized yet, so it is using before relocation serial operations but it is cleared by BSS and got the exception. To fix, change an initial stack pointer address from near the top of memory to near the relocation memory.
