F280039 can not see the AGPIOCTRLA register

Emma Wang

Hi Expert,

My customer use 80 pin F280039 so they need to use AGPIO as analog inputs.

however, the sample voltage is not matched with the voltage we test on that PIN.

software I use adc_ex1_soc_software and change the sample to B5.

I suppose on 80pin device, it should be highlight row.

I first sample a regular ADC pin and the value is right, then I sample GPIO20/B5, but it is wrong.

And we want to check the GPIO setting status. 

GPAAMSEL and GPHAMSEL are all set to 1, but we can not see the AGPIOCTRLA information

CCS version: 11.0.0.00012 

Could you kindly tell me how to see this register and where I did wrong?

BR

    Hi,

    Thank you for reporting the issue. This is a bug in the .gel file. I will raise a ticket to get this fixed.

    As a workaround, please update your gel file as follows. To view Gel files : Tools->Gel Files

    GEL_MapAddStr(0x0005D000,1, 0x800, "R|W|AS2",0); /* Device Config Registers */

    to

    GEL_MapAddStr(0x0005D000,1, 0x810, "R|W|AS2",0); /* Device Config Registers */

    This function is part of f280039_Memory_Map function in the .gel file

    Regards,

    Veena
