≪RD33772C14VEVM≫ No voltage is applied on FS26

[Itaru]

Dear NXP

 I am having trouble writing to the microcontroller board. (RD33772C14VEVM)

I connected 12V, but 5V was not supplied from FS26 from S32K, Unable to write to microcontroller.

Could you please tell me the correct way to connect?

Thank you in advance.

Dear Itaru,

please check if there is a supply voltage for the FS26 SBC. Please measure the voltage on the TP25 against GND. 

If you will measure 0V, please apply 12V and GND to the pins K30_12V_L and GND_KL31_DOWN respectively on the X-14BMS-EMU board connected to the J5 connector on the RD33772C14VEVM. 

Please check voltage on the DEBUG pin on the FS26 SBC. You can check it e.g. on the R88 resistor against GND. For the beginning it is recommended to start the FS26 SBC in debug mode. For this the voltage on the DEBUG pin must be between 2.5V and 6V before the power is applied to the FS26. Please refer to the Table 214. in the FS26 full datasheet. 

With Best Regards,

Jozef

Problem solved.
The wiring to K30 (J5_1) and KL15 (J6_1) was insufficient.
I'm so sorry for confusing you.

Hi Itaru,

sorry I only saw your answer now. I see you have solved the issue. Thank you for the update. The 12V for the X-14VBMS-EMU board was needed right? Or some other pins needed to be supplied as well? 

With Best Regards,

Jozef

Dear JozefKozon

I solved it using the method you taught me.
The 12V to other pins was not required.
I appreciate it.
