Hi,We are using the STM32MP157CAA3 SoC in our design and are having some Ethernet issues:As we had problems sourcing the Realtek PHY from the reference design we use the microchip LAN8830T-V/PSA Ethernet PHY which should support Gigabit Ethernet.When...
Dear,Some images are not shown on STM32 MPU OP-TEE overview and STM32MP15 OP-TEE overview.Thanks!
Hi st friends: stm32mp135f-dk bord use pmic STPMIC1D, but it is too expensive than STPMIC1A.can i replace STPMIC1D with STPMIC1A
I am using Baremetal.On my custom board, I successfully loaded the driver for the OTG USB device as a printer. When it succeeded, the code size was small, so I worked on it as a test in the SYSRAM base without any issues (I did not use USBX).However,...
Hi, I usb buildroot(branch: st/2023.02.2) to buid my system.I want to know how to configure to enable secure boot.if i just enable TRUSTED_BOARD_BOOT=1MBEDTLS_DIR=$(MBEDTLS_DIR)then compile error as follow make[2]: *** No rule to make target '/hom...
The issue I am having is BKPSRAM is not retaining the information I write to it after a power cycle. I can read and write to BKPSRAM after I set it to non-secure in optee, removed the power features in pwr_regulator, and I enabled the CLK bit. I have...
Hello,I am trying to use I2C2 peripheral with DMA2 streams 2 (Tx) and 3 (Rx). I am also using OpenAMP to communicate with A7 core, which runs Linux.A short time after launch, a Hard Fault is triggered. I noticed this only happens when DMAs are initia...
