Hello,I have a STM32MP2 platform with A/B partitioning for TF-A, metadata and FIP.I'm looking for a way to generate a test FIP and install it in FIP-B bank, have TF-A load it, if this FIP contains a bad signature or other error that will prevent Uboo...
Dear,I'm starting with OP-TEE on STM32MP15x line. I bring-up the board as described here and built the optee_example_hello_world as described here. However, I got the error code below:TEEC_Opensession failed with code 0xffff0008 origin 0x3Checking th...
Hello,I am trying to generate output with adjustable pulse width using One Pulse mode.The output pin is in a Pull-Up state, with an initial state of High. When One Pulse mode is activated, it outputs a Low signal for the specified duration.However, t...
Even if I route the differential pairs, one pair will always be longer than the other.Should I route an extra path, like a sawtooth or tromebone on the shortest pair to make booth differential pair equal in length?I see that the STM32MP1 dev-kit does...
I created a st-image-qt image using the STM32MP Distribution package and X-LINUX-QT add-on for the STM32MP157F-DK2 board.I could flash this image using the dd command in Linux and my target board is running correctly.On the other side, I created a qt...
hi,I'm currently designing a custom board using the STM32MP157F MPU, and I'm referencing the schematic of the STM32MP157F-DK2 evaluation board. I'm stuck on identifying a specific component with a 0603 footprint. Is it a 0-ohm resistor? Additionally,...
Hi,tI am trying to understand maximum PTP clock frequency. On page 5122 of the STM32MP2 the maximal frequency defined as 100MHz, but on page 1037 (RCC section) the maximal clock frequency of clk_eth1_ptp_ref is 200MHz. Which one is correct? Can I hav...
Hi,I am working on STM32MP133FAFx . I have integrated PMIC and getting 1.35V voltage to DDR. I am using bare-metal environment without OSAlso configured required registers for DDR with below values for my hardware,DDR_MSTR 0x00040401DDR_MRCTRL0 0x00...
please explain the steps on how to boot the image in sd card for stm32mp157d-dk1 and also which os should i need to use for programming
Hello I got succeed wlan0 connect to my phone just yesterdayPing 8.8.8.8 was worked and etc ok(without booting make 1m30s timeout)But today it is not working at all with just doing same beforeAfter enable and start wireless config with systemctl enab...
