Posted on February 23, 2015 at 17:51 I am starting using the crypto library and with a STM32F407 device I don't have the hw hash peripheral and I must use the software library My version: M4_CryptoFW_RngHW_2_0_6.a My code ...
Posted on January 04, 2015 at 21:24hi every oneas you know there are many crypto libs with supporting from crypto algouritms like: AES,DES,3DES &...such as wolfssl,cyassl,cyclone ssl,stm crypto lib(for stm devices ) & ...my question is whats differe...
Posted on December 17, 2014 at 02:50In my stm32f405 level 1 is active.I can't updata mcu flash.I need change RDP to level 0 to reprogram. Anyone can help me? thanks. #stm32f4-rdp
Posted on November 21, 2014 at 08:06Hi,I'm experiencing strange issues with a product based on STM32F407. When doing short power outages to the PCB (uses 24VAC), it sometimes erases or corrupts flash page(s) that are used for eeprom emulation. Pages...
Posted on November 10, 2014 at 15:03Hi, I'm having a problem with the CMSIS peripheral library call to set Readout Protection on STM32F10x: I call FLASH_ReadOutProtection(ENABLE) I have put a flag into this function to verify that it's setting OB->R...
Posted on October 30, 2014 at 14:58I want to implement the IAR example for ST32Fx ''Calculate CRC32 as in STM32 hardware (v.5.50 and later)'' http://supp.iar.com/Support/?note=64424&from=note+11927 The problem I don't use a fix address for end of C...
Posted on October 27, 2014 at 22:47I need to do a CRC calculation. So I want to use the CRC calculation unit in the MCU.It is pretty easy one. Just active the CRC clk and then invoke word into CRC->DR .I want to see if it work O.K. so I reset it to ...
Posted on October 28, 2014 at 17:38I want to calculate a CRC over the whole Flash Memory (16kB) of a STM32F030F4. I works fine up 8kB. Putting Values >8192 for BufferLength into CRC_CalcBlockCRC(uint32_t pBuffer[], uint32_t BufferLength). The progra...
Posted on October 24, 2014 at 23:18I want to use the CRC example of IAR ''ROM size save with CRC32 Note 52791'' from my Boot.The problem is that the intvec area set on start of the APP ROM but don't get into the CRC calculation.Today I see that the ...
Posted on October 20, 2014 at 13:51I want to make a CRC check over the APP FLASH area (I use a BIN file) to know that my APP update O.K.For that I have some question.1. Does the IAR has an option of giving me the CRC of he BIN file I made ?2. How c...
