I am designing a board using STM32MP1, STPMIC1A and LPDDR2. I want to use 3.3V VDD not 1.8V as most of peripherals are 3.3V. I am following example in AN5031 Figure 32 LPDDR2 VDD1 is powered from LDO3 in bypass mode which is powered by VDD 1.8V. I pl...
hi dear Friends, here is anyone know how to can make one Cortex A7 to run Linux and another Cortex A7 just to run other, such as algorithm without Linux. two cores run separately.thanks
Hello,I would like to use the UART7 with A7 on the STM32MP157C-DK2 with the openstlinux-20-02-19 ecosystem. Therefore i tried to include/enable the UART interface in the device tree but it is not working correctly. I configured UART7 in the stm32mp15...
Hello everyone.I am modifying the distribution packages of 157C-DK2 and 157C-EV1 for my project.When I previously configured my rootfs using buildroot and debian-jessie, I proceeded as follows(other boards).Packages that can be configured using bui...

APT-Get returns cannot find packages for everything. add-apt repository in not found.Any help would be appreciated.
Dear all, I am looking to use the STPMIC1 in one new STM32MP15x design which will spend most of this time in standby mode. I am looking for STPMIC1 buck efficiency at light load (~1mA). In the datasheet there is numbers only for 150mA, 750mA and 1A. ...
Hello,has anyone successful booted linux v5.4-stm32mp-r1 on the stm32mp157c-dk2 board?If so can you please provide me a working config?I am trying to switch from the 4.19 kernel to v5.4-stm32mp-r1 but the boards freezes after trying to load the kern...
