TEF82XX RF init failed

WenChao — Tue, 16 May 2023 08:55:59 GMT

MCU：S32R45,RF :TEF82XX SDK：S32R45_RSDK__1.0.0 function：AppRfeInit(0, RSDK_RFE_STANDALONE);

Error code error was reported during RF initialization.

Error code info： 65795/**< ADC calibration timeout failure .could you help with it?what should I do?

Hello,

Could you share more info on the issue?

Is the HW from NXP or custom design?

The calibration is described in reference manual:

What is the outcome of debugging? CALFAIL flag is set? etc...

Best regards,

Peter

(1)HW ：custom design,2 TEF82XX cascade

(2)if calstat reg fail,how can I fix it?

Hello,

(1)HW ：custom design,2 TEF82XX cascade

Does the calibration fails on multiple devices or on just one?

(2)if calstat reg fail,how can I fix it?

MSR[CALFAIL] = 1 means a calibration fail and a determined calibration value is out of internal defined limits. It also means that the ADC health may not be good and may not meet specifications.

I would first confirm that issue is present on multiple samples.

If yes, the check the steps to see where the fail happen.

The results of individual steps are also updated in CALSTAT register (CALSTAT[STAT_n]). The result of the last failed step is dynamically updated in the same register.

Best regards,

Peter

calibration fails on multiple devices.
(2) I have tried S32R45_RSDK_1.1.0, the error code is RSDK_TEF82XX_ADC_CALIBRATIONFAILED, /**< ADC calibration failure */
So does it mean that the ADC health may not be good and may not meet specifications?
I am researching The reg CALSTAT register .

Hello,

Yes, that could be the case.

Please get in touch with NXP engineer who did your design review to confirm if your custom board is according to specification.

Also are all the voltages in datasheet specified range, when the calibration is started?

Best regards,

Peter

thank U very much. It helps me a lot.My question are that :

1. ADC calibration is only internal error reporting of TFF82. This design only provides external 40MHz crystal oscillator, is it related to this crystal oscillator? Or does it have to do with RF routing?

Ahh, ok now I see. I get it all wrong.

The issue is not from uC but from AFE.

The ADC calibration of TEF82xx is described in TEF82xx reference manual:

The details on ADC calibration are in chapter 4.7.1 ADC calibration

Since I am not familiar with RSDK background calibration, its hard to say, but I expect there must be some parameters set for calibration.

Could you share how you do the background calibration?

Apart from this, it is always good to submit a ticket at NXP web page as then you can get in touch with RADAR team directly.

Best regards,

Peter

HI~ I used rsdk_1.1.0 and I didn't change any REF setting value, the REF setting value is in C:\NXP\S32R45_RSDK__1.1.0\RFE_abstract\RFE_driver\src\tef82xx\bc\inc\bc_conf.h,

when I change the ADC calibration bigger,It still reported the same error code .what should I do?

2 how to submit a ticket at NXP web page as then you can get in touch with RADAR team?

3 .sometimes it reported RSDK_TEF82XX_SYS_MCLK_INTEGRITY_FAILED, /**< MCLK for serializer(LVDS/MIPI) is not within range, is it relate to ADC calibration error?

Hello,

Ok, I am not sure here what is wrong as you have your own design.

Best would be to rise ticket for RADAR team.

Hello,

OK, there must be some issue with your firewall or so.

As the guidance is on the same community as this thread.

Here is the basic screenshot where to find ticket:
