Hello,
How can I change the LSB / MSB order of DOUT Modules in mios_srio.inc

Here the required modification:

and attached a precompiled .hex file

Sorry,
I tried that yesterday without success, but I am not sure.
I test it with dout_buttons_v1c application and the result is the same as with unmodified mios_srio.inc
SR# 1 Pin#0 0x00 let lit a LED on physical Pin 7 (QH) on a 74HC595
…
SR# 1 Pin#7 0x07 let lit a LED on physical Pin 15 (QA) on a 74HC595
that are the right results for standard mios_srio.inc I guess.
but I get this for both cases modified and unmodified.
I have also tried to change the DIN bit order with same effect.
It seems that nothing changes.
What about the applications, are there any changes to make?
chris
I tried that yesterday without success, but I am not sure.
So, you compiled MIOS by yourself and uploaded it to your core before uploading the application?
If this modification hasn’t caused an effect, then I assume an handling error (please describe more exactly what you did to clarify the issue).
Since I assume an handling error, I attached a precompiled .hex file so that you can easily compare the results.
Before continuing with speculations, could you please give me some feedback if the .hex file I gave you is working at your side.
There are no other changes which are required, it’s really straightforward.
Best Regards, Thorsten.
Yeah,
I wondered by myself but the precompiled Mios Version do the same.
I have also think about a upload failure, but the precompiled Version shows no longer the “READY.” Message first.
And so I think all is gone right by uploading.
I will now have a try with Linux and MIOS Studio 9 to upload, because I can’t use the core feedback feature with my old Win 98 
and Studio 7.5
Later more …

Shit I can’t believe that.
I’m so sorry
Yes it works, now.
MIOS wasn’t uploaded right to the core, I don’t know why.
Most changes (try to learn assembler the last days :D) on MIOS or MB64 takes a small effect and I thought the code was proper uploaded to the core.
Thanks for the help Thorsten and best wishes for the coming decade.
