Hello, In our LPC55S69 project , using Freertos, we are encountering random bugs in the .POWER_EnterPowerDown API function.
Versions used :
At first, POWER_EnterPowerDown seems to work well. However, sometimes, the CPU gets stuck in the function without effectively going to power down (we know this because the CPU current alone is about 4mA).
Thanks in advance for your answers,
Pls refer to the following remarks. I suppose that the pending interrupt leads to the issue that you can not enter the power down mode sometimes not often.
so before you can the power down function, you can clear all the pending interrupt.
Hope it can help you
