AM2634: SOC_enableAdcInternalReference Undefined in MCU SDK 10.0.0.35

Tom Tatakis

Part Number: AM2634

Tool/software:

I was using MCU+ SDK for AM263x 9.2.0.56 and all was working. I tried to upgrade to MCU+ SDK for AM263x 10.0.0.35 but I get the following undefined symbols when I build.

undefined                      first referenced
symbol                            in file
---------                      ----------------
SOC_enableAdcInternalReference ./syscfg/ti_drivers_config.o
SOC_enableAdcReferenceMonitor ./syscfg/ti_drivers_config.o
SOC_getAdcReferenceStatus      ./syscfg/ti_drivers_config.o

Is there some other library I need to link in or some other configuration item I need to set up? Perhaps in Syscfg?

Hi Tom,

As I can see the APis are still present in SDK, no change on the SDK side.

Perhaps could you try to do a clean build again.

The problem here tuned out to be compiling against V10 sdk and linking against V9 sdk. This happened because there are multiple places in CCS project files that must be updated. Once I found those, I got things built and linked against V10.

But, the application does not run and hangs during sysinit in ClockP_freertos.c, line 243. The value of the timer wraps prior to getting to the endTime (which is a very small number ~1682) so the loop never exits. Any ideas for that?

Debugging a bit, when the value gets computed at line 268, the value of gClockCtrl.timerReloadCount = 0xFFFF9E57 seems like a large number. Is this correct?

Glad to know this Tom. I was on vacation so I could not reply earlier. Yes Projects have dependency for SDK version, syscfg and compiler, they need to be set properly.

Could you provide more context, are you using any SDK example as start point reference.

I believe it has been fixed in SDK 10.1. See https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1459301/mcu-plus-sdk-am263x-mcu_sdk-10-hangs-during-system_init-when-more-than-one-adc-is-added-in-syscfg/5602106#5602106

I will mark this as solved and open a new request if needed.
