Posted on November 24, 2017 at 15:08I have a simple project that toogle a LED. I try to add software protection to it.Basically, it does :main(){ Init_GPIO_for_LED(); LED_ON(); while(i++ < 10000000) {}; // yes, ugly LED_OFF(); while(1) {} //...
Posted on November 22, 2017 at 14:23Hello all,Our product is being programmed on test bench and after that it is locked setting the readout protection to level 2 (RDP level 2).My question is - is it normal for this process to take about 3 minutes?Ar...
Posted on October 23, 2017 at 10:41Hi,I'm using X-CUBE-CRYPTOLIB 3.1.0.All RSA_PKCS1v15_* functions uses a 'membuf_stt *P_pMemBuf)' parameter.The documentation says : 'The structure pointed by P_pMemBuf must be properly initialized.'In the examples ...
Posted on October 19, 2017 at 11:21Hello,I am using the STM crypto library X-CUBE-CRYPTOLIB (there are several libraries and I could not find out which one was recommended so I picked the most recent one) with an STM32F417.I can't find any informati...
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:/...
