Subject: [PATCH u-boot-mvebu v2 0/4] turris_omnia: Disable MCU watchdog in SPL when booting over UART
Date: Mon, 16 Aug 2021 15:19:36 +0200 [thread overview]
Message-ID: <20210816131940.24206-1-marek.behun@nic.cz> (raw)
Hello Stefan,
while debugging Omnia, when sending U-Boot over UART, some USB-TTY
controllers are too slow and Omnia's MCU watchdog resets the board
before U-Boot proper is sent.
This patch series changes Omnia board code so that when booting via
UART, we disable MCU watchdog in SPL, prior loading U-Boot proper.
Changes since v1:
- added patch that moves disabling MCU watchdog in normal boot from
board_init() to board_late_init(), so that it is disabled after
U-Boot enables the SOC watchdog
