From 3a6f440dd3709efa8ea3851e9baf8e774f798fd1 Mon Sep 17 00:00:00 2001 From: Tejas Bhumkar Date: Tue, 9 Apr 2024 15:18:26 +0530 Subject: [PATCH] configs: zynqmp_kria: Deactivate CONFIG_SPI_FLASH_BAR The Kria board features a recovery application that activates when the FW_EN button is pressed. Upon power-up flash operates in 3B mode, However, the recovery application changes it back to 4B mode. Currently, after a reset, u-boot activates CONFIG_SPI_FLASH_BAR and assumes the flash is in 3B mode. However, there's no code or reset lines connected to the flash that could return it to 3B mode. To resolve this issue, changes were made to disable CONFIG_SPI_FLASH_BAR, which activates 4-byte opcodes.
