What is the value of the input impedance of the OP-AMP inside the STM32U535 in follower mode?

2024-04-02
HiThe DataSheet doesn"t give the input impedance of internal OP-AMP in follower mode.The only value is for PGA mode.There is a similar question about STM32U575 on the forum but not answer... Thanks for your help have a good day. Aurélien

Unable to write binary in non secure FLASH using CubeProgrammer in RDP 0.5

2024-01-15
Hi everyone,The MCU on my custom board is an STM32U585. I put RDP mode to 0.5 in order to debug the product application with CubeIDE (our custom bootloader is in secure world).RDP regression to level 0.5 works fine (non-secure memory is fully erased ...

How to properly configure STM32U585 to use DMA in secure mode (TZEN = 1) to send data from internal Flash (non secure zone) to Hash (in secure mode)?

2023-02-13
Hi,I want to know a properly way do to that.If i use standard configuration I run hard fault as soon as DMA start (linklist mode) (HAL_HASHEx_SHA256_Start_DMA).I put Fault Analyser details Source/Destination secure bit are set before calling this fu...

Hi,I want to compute APP's hash (SHA256) from my Bootloader using DMA.I have 3 non adjacent zone to process the HASH.If I use one node and call HAL_HASHEx_SHA256_Start_DMA inside HAL_HASH_InCpltCallback, I can compute my HASH.I hope I can use link li...

Hi,our porject use TZEN =1;A custom Bootlaoder (secure app) is executed at begin and after we call a non secure Application.The non secure Application as already been tested/validated with TZEN = 0.This application use GPDAM channel 10 ro read data f...
