power_mode_switch_s32k144 print function not working

thailivenkatesh8 — Thu, 27 Jan 2022 09:01:04 GMT

working on low power mode SDK of S32k144 in which print function(print((const char *)MENU_MESSAGE ADD_MESSAGE);) is not working not displaying any messages on putty and as per code i set baudrate as 9600.unable to see any response and readoptionconsole function is also not executing.is there any problem with this SDK code.Please support this issue to solve the problem.

Hello @thailivenkatesh8,

Can you test the SDK power_switch_S32K144 example as is without any modification?

Just to be sure, do you use an EVB or your own custome board?

Do you select the correct port?

Have you tried with a different terminal emulator?

You can scope the LPUART1_TX pin to see the transmitted data.

Regards,

Daniel

Hi Danielmartynek,

I am using Electronika distributor NXP board ,for EVB at PTC13 SW3 is there for My board added Switch at PTC15 and used Default SDK without changing the code couldn't executed the print statements and observed no data on TX pin.

in Second case edited code for PTC15 as input and external interrupt as rising edge in this case also print statement is not executed.

Hi @thailivenkatesh8,

Which version of S32DS IDE and the SDK do you use?

Thanks,

BR, Daniel

Hi Danielmartynek,

Using S32DS_ARM_v2.2 IDE & S32SDK_S32K1xx_RTM_3.0.0 SDK driver examples power switch mode .

I just tested the example (RTM 3.0.0), and it works as expected.

What EVB version do you have?

You should find labels on the board.

Also, please read the maskset number on the MCU package (it should be one of those: 0N77P, 0N47T, 0N57U)

Thanks,

BR, Daniel

Hi Danielmartynek

We are using

EVB Version: Electronika BMS V 3.0-14S &

Maskset number on the MCU package:0N57U.

Thank you for the information @thailivenkatesh8,

I can't find any documentation to the board online.

Does it support any USB emulated UART like the NXP S32K144 EVB?

Anyway, if you use the SDK example as it is without any modification, you should see the TX signal at PTC7.

Unless there is something different connected to the pin, which I can't tell as I don't have the schematic of the board.

Regards,

Daniel
