I'm attempting to enable the SRAM2 parity bits on an STM32L552, and any time I call HAL_FLASH_OB_Launch, the chip hangs. I've also tried directly setting the OBL_LAUNCH bit in the NCSR register with the same results.I've looked through some of the L...
This is the data I recorded with WireShark. As shown in the picture, when I send HID packet once (len=91), the USB will send empty data packets indefinitely (len=27), then trying to send packets from host to device (out direction) will cause the tran...
Can STM32 USB device (ACM) be configured as a LOW SPEED device? It seems like USB SW and HW doesn't support configuring a low speed ACM device. Any help is appreciated in advance. From page 1953 of Ref. Manual:
STM32L5x2xx processor.STM32CubeIDEVersion: 1.10.1Build: 12716_20220707_0928 (UTC)Program structure:Main.c calls CPP_LINK (a C++ routine) that enables system level drivers (with ThreadX mutexes), then starts main ThreadX task.C++ classes own ThreadX o...
SWAP_BANK for the STM32L552 is a bit in the eeprom, but we want to swap the flash banks in an own bootloader dynamically and do not want to expire the eeprom's lifetime,Any option to swap the memory without eeprom settings?
creating a project (say from an existing *.ioc file), the first few times work well, but I use either Azure or FreeRTOS, both situations produce identical results.After a bit, I get 9 errors, all because of duplicate definitions or routines.For an L5...
I'm trying to transmit a 4D array of floats from an stm32l552zet6q to a PC using a USB connection. I can collect the array elements and store them, but when I pass the array into the transmission function, I don't see the same elements.This image is ...
Hello,I am trying to interact with the FDCAN bootloader of the STM32L5.I had no issue with the CAN bootloader of the STM32L4 (AN3154), but with the STM32L5 I am unable to even get an ACK from the target. 1) According to AN2606 Rev 47, the bit-rate s...
Why the API for FreeRTOS middleware keeps changing every now and then? You barely start to wrap your head around an API, a new one gets released. I had to generate the initialization code from CubeMX, as it makes life much easier especially if you wa...
We are building a test card for a host that embeds the STM32L552 microcontroller in it. The data lines are broken out and VDDUSB is tied to the same voltage as the VDD for the MCU. Do we need to use VBUS in this case? Please advise.
