Hi There,
I just finished fixing the issue of DCDC can't enable two weeks ago, and now I have a new issue that is LED_LOW can't disable(see below).
The program will be crash when the program runs here. By the way, the circuit board was designed by myself and I use the BUCK mode. I checked my circuit board, and I found that the output voltage of pin 5 and pin 6 of the chip is 1.18V. Meanwhile, I have checked the document of DA14531, and I haven't found any indication that 1.18V is correct. I attach my schematic of the circuit(see below).
If the program runs nomally, what is the external output voltage of pin 5 and pin 6? If there is no problem with 1.18V, then what could be the cause?
Thanks for your assist.
