I have just download the latest ds-5 and notice the tool chain of the Arm compiler 5 is not in, how can I enable this tool chain back in the picture? I have already tried to uninstall and reinstall again.... the tool still not there...
For your information only the Altera edition that come with the tool chain you are looking for.. you will not get this tool chain if you download the community edition.
always use the soceds installer to get the latest ds-5 that locate in teh Altera website., this is the better way than just download separately from other page.
Some times we might need to beware when download some tools which is not from point directly by Altera, as this DS-5 is not supporting only for Altera product and it cover so much product line.. there fore, those guide and tutorial that just mention for DS-5 maybe 100% compatible for Altera products.
