Hi,this one is similar to https://community.st.com/t5/stm32-mcus-products/ioselect-option-in-stm32h563-is-not-working/m-p/681099but not the same. While testing OSPI1 on our MP257 board and our FSBL I found thatMSEL in OCTOSPI1->CR is ignored.CSSEL an...
Is there a Global Exclusive Monitor connected to the M33 and the A35 cores?Any documentation for it?Thank you
We have some devices based on STM32MP257 SoCs that connect to a 100 Mbit Ethernet network via ETH1, where ETH1 is going straight to an RMII PHY. Pins for ETH2 are reserved, but are not used/not connected. Some of our devices work rock-solid as except...
There is official errata named "2.5.6 Indirect write mode limited to 256 Mbytes" where indirect OSPI write requests for addr >256MB are written to invalid target address. I tested the behavior and it seems address is effectively truncated to 28bits. ...
Product:MCU/SoC: STM32MP2Description:In our ST Linux environment, the hantro-vpu driver registers:/dev/video5 -> VDEC (H.264/VP8 Decoder)/dev/video6 -> VENC (H.264/VP8 Encoder) We want to implement direct V4L2 API usage for H.264/VP8 encoding and dec...
Hi,I have a OTP provisioning script that wrote OTP 1 with value 0x000000ff, executing a partial close of security state B. The board now passes ROM/FSBL/OP-TEE/U-Boot but resets when the Linux kernel probes the first RIF-protected peripheral (HPDMA3...
I am trying to collect images from a MIPI camera that is not supported by default on the STM32MP257F-DK, but for which I have a driver. With that driver, it's seeing the camera as an attached device, and I can see it in the dmesg output and also as /...
The STM32MP135 is powered by PMIC1A. After initial power-up, the voltage at BUCK4 is normal at 3.3V, but during U-Boot flashing, the output voltage at VOUT4 drops to only 2.4V, causing the flashing to fail. The VDD and VDDQ pins of the eMMC are power...
Hi, I tried exporting the IBIS model from ST website. On importing model to SI tool I can see that there is no model assigned to DSI lines. It is showing NC. Can you share the IBIS model with MIPI drivers in it. or share some IBIS model which I can u...
