While trying to program the FS8530 chip on the KITFS85SKTEVM board,I encounter an error,I get the error ABIST2 FAIL.And it gets stuck in INIT_SAFE mode.

What can be done?

Thx.

Do you mean the SBC stuck in ABIST2 phase when start up in your board?

Or can you give some picture for your error?

When i send FS_OVUVREG_STATUS message (VCOREMON_UV bit is 1) ,under voltage fault is fixed,but abıst2 fault continue.

Yes.SBC stuck in ABIST2 phase.When i sent FS_OVUVREG_STATUS (VCOREMON bits is 1),under voltage fault is fixed ,but ABIST2 fault still continue.i will share you picture fault screen.

If in the OTP just as below picture showed, in the ABIST1,you enable the monitor of VCORE/VDDIO/VMONX by OTP, in the ABIST2 can monitor VCORE/VDDIO/VMON1234 ,any error the SBC will hang. especially for the VMONX the reference voltage is 0.8V.

If fixed the Vcore UV issue,without other issue the ABIST2 will PASS.

Thanks for answer.
Yes,but VCore UV issue dont fixed.What could be the source of the problem ?

Re: KITFS85SKTEVM

guoweisun — Wed, 22 Feb 2023 06:23:40 GMT

did you test the Vcore in your board? does it match what you setting value?

If Vcore is good,ABIST2 will pass no issue.

I knows that there is no point where I can measure Vcore directly. When I measure BUCK1 it matches the value i set.

Does any error show in the GUI OV/UV or others iteam after your fixed VCORE?

Re: KITFS85SKTEVM

After opening the card I only see the VCORE UV issue.

You can check the Vcore related circuit to verify it again,I attached the schematic for you review.

I checked the VCOREMON pin. It doesn't see any problem . It is connected with BUCK1.

At the same time, I apply these steps exactly. But when I send the message to exit DEBUG mode,

1-) all regulators power on and the

2-)all regulators power off and RESET pin blinks 3 times.

This cycle continues.Something seems to be going wrong.

Iam beginner, i will be glad if you help

Please follow up the app note for operating this SBC step by step.

Better for your test used the programmed chip by NXP you can order this part instead of blank part OTP by yourself.

After familiar with EVB then you can do OTP by yourself.
