Hello, I'm developing RTOS environment of dual-core in STM32H757.To write the data, I'm using function "HAL_FLASH_Program".The stack size of the task : 512 * 4float32_t g_temp_data[70]; // the data 1. Is it common for data to be written to Flash Ban...

Hello, I solved the issue.The cause of that was the repetitive calls of the functions in an infinite loop during RTOS Scheduling, and I was wrong, so I modified the functions to be called only once during RTOS Scheduling.I previously thought the memo...
