FS8530 with FlexGUI: OTP programming error Boot Enable (BE) failed

Hi,

We want to burning/programming the OTP for FS8530 PMIC using FlexGUI.

In OTP emulation mode, everything works fine. I could send the generated script (from Excel file) to the FS8530 PMIC and the device behaves as expected.

Then I proceeded the OTP programming as follow:

  • Restart the PMIC device by turning Vbat Off and On again via SW1-switch
  • In "OTP_prog" tab, I browsed to the generated script and clicked on "program" button
  • As the pop-up windows appeared, I turned on the DBG_pin by closing SW3-switch

And now came the error: "Boot Enable (BE) failed".

After this process, when I start the device, it consumes a lot of current (~400mA) and the outputs of the regulators are not switched on.

I don't know what went wrong? and How to solve the error ?

Here is a screen shot from FLexGui.
