This is definitely a DC step processor but the message from MEMTOOL implies it is either a CA step or MEMTOOL is picking up the wrong Aurduino_TC27xX_das.cfg.
Please start MEMTOOL directly and see if it will connect to the processor.

Do shieldBuddy support the double or it supports only float? I require double precision. How can I run calculations with double precision on this board?

The double support is currently disabled but we can enable it in the next release, if required.

Thanks, Next release of ShieldBuddyMulticoreIDE? or you are planning to release some patch for that? It will be great if this issue can be fixed ASAP using some patch.

Thanks Admin...It seems that the processing speed has reduced after updating the software. Please have a look.

Hi Admin,
I mentioned in my last post that the processing speed of the board has reduced after updating the software. To check that I reinstalled the previous version of ShieldBuddyMulticoreIDE and run the code using float(run time 3 sec). On the other hand the run time for recently released v1.37 was 158 sec (same code using floats only). I think there is some issue with the v1.37 as it is making code slow. Please have a look.

This is strange. Are you sure there are no double floats in the software? The Aurix has built-in single precision floating point units so float operations are very fast. Double float operations are performed using emulation libraries and these are much slower.
We will remove the double float support in v1.38 pending an investigation!

Hi I have just received my ShieldBuddy (UK) and it is also a DC variant and so I have the same problem as Hotz. After reading the posts, I installed the latest version of the Multicore IDE and now the Shieldbuddy is not recognised by the device manager - "unknown device" - it is powered. Hitting the rest has no effect. Help please! NB the shieldbuddy was recognised, albeit wrongly, by the earlier version of the software.

Hi, if the Shieldbuddy is not recognised by the Device Manager it is likely that the DAS driver has not installed properly. This is part of the MEMTOOL Flash programmer. What Windows version are you using?

I am using Windows 10. Should I actively delete the Hitex directory before installing the new version - it doesn't appear in the Win10 apps list so it would have to be brute force? I didn't do this to begin with as I am not sure where the tool chain data etc goes.
Thanks for the help.

Yes delete the c:/Hitex directory. Then reinstall the Aurix free toolchain then the Shieldbuddy add-in for the Arduino IDE.
