I am use this code for write page with disabling WRP:FLASH_Unlock(); if( FLASH->WRPR != 0xFFFFFFFF ) //WRP is active for any pages { FLASH_EraseOptionBytes(); NVIC_SystemReset(); //according to the manual } if( FLASH_ErasePage( address ) != FLAS...
HelloSince the STM32f42xx series has no intial value for the CRC I'm wondering if there is a way to stop a crc calculation (store the DR value) and resume it by writing the DR register with the stored value and some calculation??Something like this:c...
I'm currently porting an existing project so it can be updated using the sbsfu bootloader project from ST. My userproject is using the MPU to protect the ethernet tx and rx descriptors from ending up in the d cache. However, if i enable the MPU the F...
I noticed that in STM32FLASH programming utility, there is support for a CRC bootloader command. From what I can tell in the source code and commit history, this command is 0xA1 and was introduced around June of 2014. But from the ST documentation, ...
I need to implement some BigNumber math on an STM32F4 (bn.h, conv.h, modular.h). I would like to use functions such as W8_to_Big(), StAllocBig(), and InitBig(). Unfortunately I cannot find any information on how to use these functions. Are there any ...
The user manual (UM1924) says in section 15 RSA Algorithm:There are two structures that pass keys to the functions:•RSAprivKey_stt for the private key•RSApubKey_stt for the public keyAll members of the above functions should be filled by the user bef...
Hi, I just went over the X-Cube-SBSFU material and tried to compile the example projects to get an overall picture of this function.The MCU I used is STM32F730I8 and I am using the STM32F7308-DISCO board.As only 64kB flash is available in STM32F730 s...
I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.
Dear all. How secure is STM32 MCUs to prevent hackers from dumping the firmware from the flash memory? I've searched on the internet and on Taobao (like ebay) China and I found there are plenty of companies that claim they can crack and dump the fla...
