Not showing anything on serial port about raspi3-tutorial HOT 5 CLOSED

Okay, first thing first, which tutorial are you talking about?

If I understand right, the UART1 tutorials (1-4) were okay, and there was at least one (or more?) with UART0 (>4) that worked?
Also, what kind of terminal emulator are you using? Is it minicom? Have you specified it's arguments correctly (device file exists, accessible and set to 115200,8n1)?
Finally which commit are you using? There was a copy'n'paste bug that used UART1's bin mapping for UART0 too (obviously not good, requires alt0 instead of alt5, fixed 3 days ago). Use the latest version to be sure.

Hey,
1] All tutorials before 0F_executionlevel have worked.
2]It is minicom terminal emulator
3] Yes it is set to 115200,8n1
4]I am using the recent commit
Strangely running on qemu does give me the output but not on my raspberry pi 3

Thank you for the feedback, I'll look into that!

I can confirm. I've also checked my original source, which works perfectly. I'll have to figure out what copy'n'paste bug have I done this time; shouldn't take long.

Hi btauro,

Bad news, I'm afraid. It turned out that my first test failed because of a sync error. I've compared the code in the tutorial with my original code, and there was only one difference, setting the virtual mpidr register. I've tested with and without it, both worked.
Since I'm unable to reproduce your error, I'm not sure what the problem could be. I've attached a screenshot, first I've tried my original code, then the tutorial with vmpidr code, then the unmodified tutorial. Finally I've tested the unmodified tutorial again, just to be sure.

Cheers,
bzt

Could you please tell me what could cause no display in raspberry pi3 .i guess start.S may be causing the problem

This is my config.txt
arm_control=0x200
kernel_old=1
disable_commandline_tags=1

My qemu Output

Unfortunately not working on Raspberry Pi3 for some reason

Do i require any additional files on my sd card.These are the files on my SD card
