Hello everyone,i am trying the secure user memory on the stm32h7b3 using the examples provided by ST. In want to enable secure user memory for a 230KB area starting from the begin of the flash: 0x08000000. The function RSS_API->resetAndInitializeSecu...
Hi @Tesla DeLorean ,I use the IS25LX064 OctoSPI Flash memory with the STM32H573 and i can write and read from memory using direct mode. In memory mapped mode i can read the flash correctly for 0x90000000 but writing at 0x90000000 using memory mapped ...
Hi everyone,I use the IS25LX064 OctoSPI Flash memory with the STM32H573 and after configuring the OctoSPI flash i can read the device Id of the flash successfully. But when i change the configuration of the Volatile configuration register by setting ...
Hello everyone,i am trying to read the device unique id of my stm32h7b3 mcu, but get a bus fault on line 2: uint8_t* uid_base = (uint8_t*) 0x08FFF800;
uint8_t i = uid_base[0]; Do you know what could be the problem ?
Hello everyone,I'm experimenting PCROP activation on stm32h743 following this ST-tutorial: https://youtu.be/7Wr90XFA8_Q?si=tDpqUtMdin9Oyn-PThe activation works fine but i cannot disable PCROP using CubeProgrammer.I did a RDP1 to RDP0 regression with ...
Hello @KDJEM.1,looking at the schematic the DQS Pin of the flash is not used. But enabling DSQ for write operations as explained in errata sheet 2.5.1 fixed the problem. I can now write in memory mapped mode without any errors.Thanks you!
Hmm, thanks @Tesla DeLorean , now i can read 0x1F which is the default value of the dummy cycle and after setting the new value the register value is set to the new one. The Problem was the the address width. With HAL_XSPI_ADDRESS_24_BITS it works fi...
Hi Kaouthar,the memory size is correct, it's 8MBytes. I am using the IS25LX064 Flash which has 64Mbits (8Mbytes).I set the dummy cycles to 8 for reading the volatile config register but still the same error.Thank you!
