We implemented an OTA update procedure where we provide an STM32L476 with a new firmware via serial using the Ymodem protocol in a two-image SBSFU configuration.We are executing long-running tests in which we use the same firmware image to test the u...
I ported the SBSFU to an STM32F429 and everything works but it takes almost up to 6s (!) before the bootloader exits and jumps to the main application. My application is about 1.3Mb (entire flash is 2Mb) so it is not exactly small, but 6s boot time i...
Background information : we are using STM32F407 for our product and 2 of them (out of 3) encounters the same problem: RDP level has been changed from level 0 to level 1 and stopped working without any modification from our part. Before even thinking ...
hello,this is soleiman,I have used a stm32f429igt6 and programing with "C", i have finished my project and I'm ready to sent it in the bazar for sale,so I'm really worried about steal, there is no rule about copyright in my country,do you have any ad...
Hello,I'm having trouble getting the interrupt for the RNG on the STM32F207 to trigger. Below is a code snippet of what I'm doing;.void generate_rnd_num(uint32_t *rnd_num) { RNG_HandleTypeDef rng_handler; rng_handler.Instance = RNG // Point t...
I have ported the SBSFU application from NUCLEO-L552ZE-Q to STM32L562E-DK.The single-slot partition is working fine as expected without any issue.For my requirement, I have added a second slot in OSPI flash. Changed flash_layout.h and respective file...
Hello community, how are u?Hope everyone is well and safe =)I'm developing an application using SBSFU. While testing the examples (withoout provisioning a AESKEY, only flashing SBSFU engine) i could always return my microcontroller to factory, just c...
Hello, i have have included the stm32g4xx_hal_cryp.c v1.4.0.The clock is for AES is started (__HAL_RCC_AES_CLK_ENABLE)But the AES Registers are always 0, even writting with a debugger is not possible.Do you have any advice ?With friendly regardsMark ...
For some reason, when I enable CRS Automatic Trimming my USB connection gets unstable. I need to unplug/plug back the USB several times for the PC to recognize the device. When I disable the Automatic Trimming mode and use the default HSI48Calibratio...
