From 5f14e2fe9d70afac8aa6e87319e826c7b9daa489 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Tue, 18 May 2021 15:12:04 +0200 Subject: stm32mp: stm32prog: remove all the header check for UART download This patch removes the header check for UART download; the check of checksum is not mandatory with even parity and chuck checksum for each 256 received bytes and it is only done for STM32 image (FSBL = TF-A BL2), not for FIT image. This patch solve issue of duplicated 0x100 byte written with FIP header.
