HiI am using STM32L4R9ZI for my product and I am facing an issue in updating Flash. I am using flash_l4.c as provided by CubeIDE Project along with the STWIN Kit. I have attached the flash_l4.c for reference. I am using the FLASH_update() function to...

Hi,I have a general question regarding the problem I am facing.Currently, the pSpeed Value is very small (for example 3.4E-7) and when I perform a square for such values it becomes smaller. When I pass the Square data value to the arm_sqrt_f32() func...

I am trying to download Firmware into the Flash in the form of 4KB Chunks. However, on some pages, I am unable to update Flash because HAL_FLASHEx_Erase() returning an error as I am getting FLASH_FLAG_PGSERR for FLASH_WaitForLastOperation(). It is oc...

Did you mean to say that it's incorrect for very small values?Yes. Sorry for the typo. I have updated my post nowPlease show specific examples of inputs vis outputs, and the error as you square and subtract from the initial valueI have an array of fl...

What chip?STM32L4R9ZIJ6If it has an FPU, it will be faster to use native sqrt functionsYes, it has FPU. Thanks for the suggestion. I will use sqrtf() and will get back to you with the results

I am also facing this issue. It fails randomly while copying new firmware in the flash. I am copying in chunks of 4KB in Flash. However, it fails randomly when calling FLASH_update(). I am calling __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_ALL_ERRORS);but sti...

how many LIS3MDL are you seeing behaving this way?It is occurring on all our boards You might check-first the current consumption just after the device power on (MD Bits are '11' by default).I will get back on this thing.You should also check the def...

HAL_FLASHEx_Erase() fails sometime on STM32L4R9ZI

Small Floating point values

Getting FLASH_FLAG_PGSERR when calling FLASH_WaitForLastOperation((uint32_t)FLASH_TIMEOUT_VALUE)

Hi, I am trying to bring LIS3MDL to power-down mode. I have set MD Bits to 2 of "ctrl_reg3" but still, current consumption is 1-1.5mA. I have attached a schematic of LIS3MDL . Any help in this regard would be appreciated.

Is there any way to make CMSIS RTOS V1 integrate with CMSIS RTOS V2 in an application?
