I am working with SAES on STM32U585. I am trying to make use of wrapping/unwrappinng my encryption key with hardware-secret key DHUK . This in the SAES initialization I am using hcryp.Instance = SAES; hcryp.Init.DataType = CRYP_BYTE_SWAP; hcryp.I...

I have been trying to figure out which code exactly needs to be put in SRAM4 memory region for the LPBAM tool to work. All the examples I could find only use SRAM4 and fail to explain which parts are strictly needed to be placed in that part of the m...

I am trying to reprogram a custom board with STM32F411RC over I2C using the built-in bootloader. I am able to successfully issue the Get version, Get ID and Get command and get correct response. After that when I try to do a No-streach mass erase (da...

I am working on a custom board with STM32F411RC which can communicate over SPI and I2C to the master board and acts as a slave in both cases. The master board also needs to be able to reprogram my board over I2C. Chip select signal is used to control...

I appriciate your help but it still didn't solve my issue. I still get the incorrect result when I put the line you suggested before the first call to HAL_CRYP_Decrypt. As before I have configured AES in CBC mode with 128 bit key with this the follow...

Here's the code I am running uint32_t key[4] = {0x2b7e1516,0x28aed2a6,0xabf71588,0x09cf4f3c}; uint32_t iv[4] = {0x00010203,0x04050607,0x08090a0b,0x0c0d0e0f}; uint32_t encrypted_key[4] = {0}; hcryp.Instance = SAES; hcryp.Init.DataType = CRYP_BYTE_SWA...

I have put CRYP_KEYIVCONFIG_ONCE in to my init function, and if the first function I call afterwards is HAL_CRYP_Decrypt, providing it the encrypted text which would be produced with encryption, the funtion returns all 0s. If I first call HAL_CRYP_En...

So I have figured it out. I needed to place the variable ADC_Q_Conversion_data_1_Desc of type LPBAM_ADC_ConvDataDesc_t and data buffer in SRAM4. Additionally I needed to set the variable ADC_Q_Conversion_data_1_Desc to 0. Since this is a struct, this...

I have a simple application with one queue which has one ADC conversion data block inside. The conversion is triggered by LPTIM1 which I start and stop manually. After 50 samples I expect a transfer complete interrupt. The queue is not run in circula...
