I am using STM32H753ZI for my project. My use case is I want to detect brown out reset after brownout occurs and system restarts.I am checking brownout reset flag using if (__HAL_RCC_GET_FLAG(RCC_FLAG_BORRST). My query is this flag is shared/common b...

Hi,I am using STM32F779NI and CMSIS RTOS2 for my project. Software was working well till I added code for low power mode with RTOS tick-less operation as per the linkhttps://www.keil.com/pack/doc/CMSIS/RTOS2/html/group__CMSIS__RTOS__KernelCtrl.html#g...

Hi, I am using STM32F779NI and Keil IDE. I have defined SRAM start area in Target options from0x20000000 with size as 0x80000. Now, I want to write a keyword at known location in the memory. The memory area should be selected such that incremental de...

I am using internal ADC of STM32F779NI connected to LMT86 Temperature sensor. Vref is 3.3v and ADC resolution used is 10-bit. The problem is there is always a difference with the expected ADC and the actual ADC for a given voltage. This difference is...

You mean changing SLEEP mode to STOP mode will work. Any reasoning because CMSIS RTOS2 link as shared above doesn't mention that it will work only in Stop mode? In STOP mode, all clocks are disabled which is not feasible for my application.

Thanks for the reply,SRAM has been defined from 0x20000000 till 0x20080000 (target option settings in keil to give start area and size of SRAM). So, till 0x20080000, memory will be utilized by linker. Am I right?I have tried using memory after 0x2008...

I am using STM32F779NI and Keil IDE. Target SRAM for project defined is starting address 0x20000000 with size 0x80000. Which location should be used for writing this keyword for BOD?
