Hello Iva,
it seems I have the same problem with an SDK for MK64FX512VLQ12 built via the SDK Builder: after having accepted the click-through license agreement, I get redirected to the same page I came from (the 'Software Vault') but no download was started.
Please let me know ASAP when the problem is fixed because I need to calculate the ressource usage for our project in order to make a design-in decision.
Many thanks,
Florian
P.S.: maybe, you could even just send me a version of the SDK for MK64FX512VLQ12 directly (including FreeRTOS and Ethernet).
