Posted on October 02, 2017 at 17:36My current project involves some pretty complicated logic, required for firmware update over the air. So I ended up with solution, which contains bootloader and application code, compiled separately. My current mem...
Posted on September 23, 2017 at 14:10Hello,rm0433 rev 3 and stm32h742xx.h header are not consistant about CRCDATARx.From the description in rm0433 3.3.6, is seem that there are CRDATAR1 and CRCDATAR2.rm0433 3.5 only lists CRCDATAR at offset 0x5c and...
Posted on September 21, 2017 at 13:03Hello All,I am using STM32F767ZI Nucleo Board. I am getting DCRCFAIL in data transfer using CMD53 in SDIO.Any possible reason for CRC failure? Could there be any relation to clock out from SDMMC adapter?I am able...
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 ...
