Hi,
We are using the LPC1788 controller in our applications.
If the power goes out to the controller, we need to hold some information.
For that we are using GPREG0,1 and 2 registers to save the data. We are also using RTC with Vbat(3.2V Coin cell).
But, even if the RTC works well after the power outage, the data stored in the registers is missed sometimes. This issue is occurring randomly.
Hi @PMGJ1
Thank you so much for reaching us in our community. I would like to apologize for the delay, but we are experimenting a high volume of questions these days. I really appreciate your patience.
I would like to help you, so may I know if it is possible, are you using your custom board with LPC1788 or you are using a development board from NXP ? So I can reproduce your issue on our boards and see what is going on, it is too weird that occurs randomly, it comes to my mind that it is a HW issue.
I will stay tuned to your reply, so I can help you further. Please let me know if you have more questions.
Sincerely,
Pablo Avalos.
Any update on the above problem. Please suggest!!!
