We managed to successfully run TFM_SBSFU example for the IOT02A board. We are using latest STM32Cube_FW_U5_V1.2.0.The problem is that we do not have access to PSRAM from NonSecure application when in memory mapped mode.We implemented PSRAM init by im...
Hello, I've been trying to build an application with Trusted Firmware and using Zephyr RTOS for the non-secure application i'm using b_u585i_iot02a board. After i build my application, the OSPI is not working anymore from my non-secure application. I...
Hey, I'm starting on using OTFDEC for encryption of data on external OSPI flash, the project i'm working on is based on the Zephyr OS, and as far as i can see there are no examples on how to build an application with the OTFDEC setup using Zephyr. S...
Hello,I am trying to access the MX25LM NOR-Flash chip on the B-U585I-IOT02A board via OCTOSPI2. The nCS pin is connected to PI5. However, attempting to enabe the peripheral clock for IO port I by setting Bit 8 (GPIOIEN) of register RCC_AHB2ENR1 fails...
We are planning to use an external flash memory connected via QuadSPI to the OCTOSPI peripheral of a STM32H735 (at a later stage that would be STM32H733).This will be used to run firmware and store downloaded firmware updates with SBSFU. For that we ...
