Hi,
I want to make minor modifications to the DA9062-10AM. I hooked up a I2C master and am able to read/write registers, however not persistently.
The TP is nicely supplied with 7v6. Is it possible to modify OTP of a non-blank part, or can it be locked for this?
I also noticed that read register values differ w.r.t. TP being 0v at startup, why is this?
Using smart-canvas/commander tools and dedicated programmer boards evaluating on blank parts seems a bit of an overkill for my situation.
Thank you in advance,
Arjan

Hello Arjan,
Could you confirm which GUI you are using?
When you say programmer board, you are using the ICP board?
Do you apply the 7.5V before Vsys?
Kind regards,
ED
Hello ED,
For this modification I am using a custom electronics board, part of our product development; i am directly in control of the I2C bus, doing manual register reads and writes. 7.6V on TP is raised several seconds before Vsys.
Thank you in advacnce,
Arjan van Heusden
Hello Arjan,
Which GUI are you using?
When over programming you can only go from a 0 to a 1.
Kind regards,

Hi ED,
I am using a custom application, for direct control of the I2C bus.
I am unable to set a 0 to a 1
我也不要你nderstand why i read different values when TP is set to 7.6v
Thanks for your reply,
Arjan
Hello Arjan,
So you are not using a Dialog GUI and/Or board?
The issue you might be having is down to either not using the Dialog GUI or Firmware.
Kind regards,
ED
