I have set :hostname_pn-base-files = "new_host_name"in my conf file.This seems changing /etc/hostname in base-files image. However, there is log message telling:"[ 7.249795] systemd[1]: Set hostname to <stm32mp1-disco>."Also, /etc/hosname contents ...
Hi ST!I am working with Rust on your STM32MP157. While we have this working already, this is cumbersome as we have to figure all register addresses and layouts manually. Normally, in Rust, we parse the SVD file corresponding to a chip and go from the...
ST provides eMMC partitions (besides fsbl and u-boot) : boot, root, vendor, user.I need new partition /home and want removing vendor partition.How can I get this customization ?
I have a DK1 and have wired to UART7, and got UART7 working by grafting this section (by using the CubeMX tool latest version as of a few days ago) into the existing st32mp157d-dk1.dts and rebuilding. (The real product is intended to use UART7.)===al...
Hi,I am working with the STM32MP157c-DK2. All examples are working fine, but now I would like to use custom code. I generated some code using CubeMX for the development board. I used the default settings and enabled FreeRTOS additionally. I compiled ...
Im trying to integrate the firmware we have developed into our distribution on yocto. The documentation in the wiki [1] isn't really clear in how we add our own firmware to populate the MP1 coprocessor on boot. And the eample projects that the m4proj...
