It looks like STM32L496xx.h does not have the hash peripheral definitions in it. e.g. The STM32Cube_FW_L4_V1.16.0 examples for STM32L496 HASH peripheral are all configured to use the STM32L4A6xx. Does ST have a plan to update STM32L496xx.h?, or Is...

SBSFU user app API extension · 2021-08-25

My project uses SBSFU template ported to my STM32L496 board. I need to call the crypto library from the user app. UM2262 mentions cryptographic middleware support in sections 6.2.3 and 6.2.4, but it is vague. Are there other documents that explain b...

I am using a LIS3DH breakout board that is exhibiting weird behavior. My I2C master is a STM32L496 board that has been tested OK with other I2C chips.StartupI2C init to 400 KHzScan all possible addresses via HAL_I2C_IsDeviceReady() loop Remember add...

I am trying to modify the way secure boot handles the reset cause. In the code, I find CHECK STATUS ON RESET function and a comment that reads; "Hence this piece of code must systematically be revisited and tuned for the targeted system." List of a...

I've tried to disable the XferHalfCpltCallback when using UART DMA transmit without any luck. I believe that you cannot change the callbacks, or disable them. Observations:When you call HAL_UART_Transmit_DMA(), the callbacks are set to predefined U...

Yes. Or, you can keep version 1 as the factory image and change version for field release and never increment it again.Search for SFU_FW_VERSION_START_NUM and you'll see how it's used. Look at SE_FwRawHeaderTypeDef and its Reserved member. You can...

Disregarding the CPU time, as long as the highest priority ISR does not access the RTOS API or your own hand-rolled semaphores/mutexes/etc., you should be OK. I've had to do this a couple times. FWIW, the ISR tracing functionality of your favorite ...

Well, yeah, I feel dumb. I skipped over the user manual saying "This section applies to STM32L4Ax devices only." :dizzy_face: I did however open the example project under ...\STM32Cube_FW_L4_V1.16.0\Projects\NUCLEO-L496ZG\Examples\HASH\HASH_SHA224...

Andrew,In my case, I did start with a larger-memory variant - and got it working. The NUCLEO WL55 board. I then tweaked the ST code and rewrote a couple lines per information from the manufacturer, Midatronics. Only the RF switch interface pin #defin...

RAM buffer if it fits. Look for circular buffer, head, tail pointers, etc. For flash... hmm. Same concept as circular buffer, except you need multiple buffers. Each requires its own set of pointers.In RAM, you can use two buffers, or ping pong) fo...
