Hello all, When I had a beautiful STM32U5 in hand the world was still good.But now I have a comprehension question about the STM32L0, I have an 8-bit buffer and now the fastest way to AES decrypt/encrypt this data is via DMA with active burst mode. T...
I have an STM32L073CZ that I'm having an occasional error with. I'm using the HAL libraries to program EEPROM and a number of our MCUs are seeing errors where they fail to write the first word. After that it'll start working correctly and everything ...
We are right now using this MCU STM32L051C8T6 in a mass production up to 32.000 setsRight now we have met a problem,afer all 32000 pcs have been programmed with an hex file.I was found mcu have been locked and we cannot upload new files into them. 1....
I set the start address about RAM is 0X20002000, and disable shared but execution.Than, I set a function which data is 0x20002004 to change the protected data.when system enter the function, it will reset.
In some ST documents the STM32L0X1 is listed as having an RNG peripheral and older versions of the CMSIS headers list the RNG register addresses. Moreover, enabling the peripheral and using it appears to generate random numbers. However newer manual...
Hi i am using STM32L071CZ controller and i am trying to firmware update the controller using UART protocol and during that firmware update in boot mode what all security features i can implement for a secured firmware update ,Security features which ...
I am able to run "2-Image" sample application in NUCLEO-L073RZ board.I would like to use "1-image" application due to memory restriction.But example application for "1-image" is not provided for NUCLEO-L073RZ board.Could you please let me know the ch...
Hi there,I currently use STM32L073 for evaluation and found some issue with CRC module.L073 has a CRC peripheral whose polynomial is programmable. And when I programm the peripheral as below, the checksum returns from the module doesn't match the one...
I have one STM32L4 that act as master MCU.This master MCU is set with RDP L0. I have another slave STM32L0 with RDP L1. I tried to read this STM32L0 using this master MCU but did not get any result. It seems like this slave MCU did not run the code c...
Hi,I'm not sure what is going on exactly, but I think there is either an issue with the HAL or the USB windows driver for STM32 CDC. I am using an STM32L072KBU, STM32Cube MCU Package 1.17.0. I wait until the device is enumerated (by checking the dev_...
