I have a project on my STM32WB55 and have BLE working very well (it's using the latest stm32wb5x_BLE_Stack_full_fw.bin). Everything was working great till I decided I wanted to use some AES function to hash some passwords. Basically if I have my project without the CRYP module everything works great. As soon as I add this to the init section in main, bluetooth never works again, function calls go to exception handlers.
/***************** AES 128 ****************/
/* Initialize the CRYP peripheral */
hcryp1.Instance = AES1;
hcryp1.Init.DataType = CRYP_DATATYPE_32B;
hcryp1.Init.KeySize = CRYP_KEYSIZE_128B;
hcryp1.Init.pKey = (uint32_t *)pKeyAES1;
hcryp1.Init.Algorithm = CRYP_AES_ECB;
hcryp1.Init.DataWidthUnit = CRYP_DATAWIDTHUNIT_WORD;
hcryp1.Init.KeyIVConfigSkip = CRYP_KEYIVCONFIG_ALWAYS;
if (HAL_CRYP_Init(&hcryp1) != HAL_OK)
{
Error_Handler();
}
If I take the above out, everything is great. As soon as I do this, no more bluetooth. Anyone have any thoughts?
