Make reset to ZSK one more time or two

 

Hi sir
Could you explain this, please?

 

Dear Mr. Shock I read your posts on how to reset the cpu of the zsk board I need your support to reset the electronic one that helps me, it can't understand your reset scheme, I attach information about the microprocessor and image of the zsk.
very grateful for your support

 

please look carefully the Pins schematic in the Datasheet, the PIN= RESET + PIN =GND or Ground.

That is .

However as I did explain you befores: Test the regulated power supply in the terminal Vcc for CPU in tolerance + 5Vdc + CLOCK or CLK pin

Blessing.

 

Please do it simple

 

You dont need to do all that , on zsk board ghere is X11 plug try to short circuit in the same time the 9_10 pins and 11_12 .
Turn on again the machine and the issue will be done

 

Dear Mr. Chock, I have received your answer to reset the zsk board cpu, but I have another question, the jumper according to the image that I attached has to be in that position or removed at the time of doing the reset.
Thank you and waiting for your kind response.
Greetings

 

Sir if you remove the jumper at the same time, the jumper, YOU WILL NOT MAKE THE RESET.

In short, you will have the jumper connected to ground in order to RESET , must be executed.

I strong recommend you, as i did explain before : 1) test the regulated power supply in Vcc +5vdc + CLOCK in Mhz!!!, OTERWISE the RESET WILL BE FAIL, AND INEFFECTIVE!!!

 

Dear Mr. Chock, according to the attached image, the position of the jumper is it in the correct position? the electronic that is seeing it is not sure if it is the correct position.
waiting for your kind reply.
blessings.

 

Yes Sir, is in the correct position!

Remember this is a secret , developed by me, for to RESET any CPU or Microprocessor!

 

Dear Mr. Chock, very grateful for your support, we are going to execute your instructions, hopefully it will be the solution.
blessings!!!!

 

OK, remember Test the Regulated power supply ++Clock of CPU!

Great1

 

Please sir do that and your issue will be done

Switch off the machine ،do this procedure for 30 seconde carefully and switch on the machine again

Good luck

 

Remember at the same time .
Put jumber on 9_10 and 11_12

 

Mr. Adil, thank you for your recommendation on the reset through X11. I send you a photo to help me identify pins 9-10 and 11-12.

thanks for your support

kind regards

 

on the X11 sheet, pin number 1 is mentioned on the right and it is from there that you can start calculating from right to left.
you will find attached an instagram link and a demonstration and description to understand.
