MCU-PLUS-SDK-AM263X: Using more than one ADC

Hi Saman, 

This is not an expected behavior, we have multiple examples in the SDK that makes use of more than one ADC, configured via syscfg, like the AM263x MCU+ SDK: ADC High Priority SOC (ti.com) AM263x MCU+ SDK: ADC Multiple SOC EPWM etc. 

Please try one of these examples and see if you have same issue.

(To be precise in the "Drivers_adcOpen" and when it executes "ClockP_usleep(500);"

Could you please provide more details on,

1. your syscfg configurations,
2. which ADCs are you trying to enable and
3. which ClockP_usleep statement is it hanging on, like when multiple ADCs are configured, at which ADC configuration is this hanging on? 

I am assuming you are using the latest version (9.1) for MCU_PLU_SDK and your DPL configurations are working. 

Hi Mihira,

How can I send .syscfg file specifically to you?

It does not matter, If I enable more than one ADCs, the problem will pop up.

in " Drivers_adcOpen()" in "Debug/syscfg/ti_drivers_open_close.c"

The version is SDK 9.0.0.33

Have you tried these SDK examples? what is the behavior that you are observing?

For now, you don't have to. Please compare ADC, DPL configurations against one of these examples. If any configurations more than these, you can list down here in the forum and we can check. 

Thanks and regards,

Madhava

Hi MIhira,

The example code is working fine,

And I cannot see big difference in ADC configuration in SYSConfig.
