3. Known Problems and Limitations
This section lists known problems and limitations of this release:
The target auto-boot feature does not work with
picocom
as that terminal application causes the U-Boot auto-boot count-down to be interrupted, effectively rendering the auto-boot feature not working.Workaround
: Theminicom
terminal can be used as an alternative terminal application, which doesn’t cause the issue.
ID: STM32MP2-5.
