Posted on March 24, 2016 at 14:16Hi, I cannot manage to enable the RNG that is on my STM32F407VG. Using https://github.com/libopencm3/libopencm3-examples/blob/master/examples/stm32/f4/stm32f4-discovery/random/random.c, setting the RNGEN bit in RNG_C...
Posted on July 21, 2017 at 15:49 Hi all : I am using the STM32L4xx Stm Cube drivers for AES-256 ECB encryption on the STM32L4 Although the encrypted data comes out perfectly, the decrypted encrypted data is not the original plaintext. To be clear...
Posted on August 07, 2017 at 13:57Hi forum,For my project, I use the STM32L0G6 MCU. My goal is to program the device, and then protect it against read-out, such that no copy of the firmware can be done.I also use the embedded bootloader ( see http:/...
Posted on August 22, 2017 at 10:11More specifically we are interested in the AES256-GCM algorithm on STM32F777.Looking at the User Manual (http://www.st.com/content/ccc/resource/technical/document/user_manual/group0/f9/6e/f2/a2/b4/ec/49/c0/DM0021506...
Posted on May 29, 2017 at 21:16I'm trying to use AES with STEVAL-IDB006V1. I'm using some utilities from stm32l1xx_aes_util.c file.I have enabled RCC_AHBPeriph_AES with the command RCC_AHBPeriphClockCmd(RCC_AHBPeriph_AES, ENABLE);but when the applic...
Posted on August 04, 2017 at 11:48Hi,I have a legacy device, a bootloader, running on a STM32F101CBT6.I don't have it's code, so I'm not sure of what's it doing exactly... but I know it locks the flash.My goal is to upload an application, with a pay...
Posted on July 13, 2017 at 18:04Hi all,I am using the STM32L011G3U6 with 8kB FLASH.We deliver this chip programmed with a firmware that is read protected (RDPROT = Level 1)Our customer should be able to write certain data in predefined non-volatile ...
Posted on June 27, 2017 at 18:17Hi St communityWe have a custom board based on STM32F429 that runs a gateway application between a wireless transciever and an ethernet link.To check for frames integrity we use a CRC16-CCITT algorithm, each bytes req...
Posted on June 23, 2017 at 04:01Hi everyone!I'm using STM32F105 MCU , and I'd like to explore built-in DFU featureWhen I set BOOT0/BOOT1 pins per datasheet and reboot the MCU, the feature always works ok no matter how read out protection is set in o...
Posted on June 21, 2017 at 10:14I tried to enable the read out protection on a stm32w108 using stm32 stlink utility. The problem is that the process fails, and I end up having three locked full erased chips. The option byte reports that rdp is enabl...
