Ticket Name: How to use IPU1_0 instead of A15_0 to process NDK in TDA2x-EVM Query Text: Hi all, When NDK_PROC_TO_USE=a15_0 by default, the target works normally. But when I set NDK_PROC_TO_USE=ipu1_0, the target halts after run. ipu1_0 is halted at Network_waitConnect() and the return status is 0. Meanwhile, there is no longer any response from UART when I try to send cmd to it. I have tried ipu1_1, the same result appeared. I did have done "gmake -s depend" before "gmake -s" as the guide metioned. my VSDK version is 2.08 I wonder if someone could help me. Thanks a lot. Responses: Hello Benz, Can you send output of gmake -config after configuring NDK_PROC_TO_USE=ipu1_1? Also have you tried doing clean build after making changes? (remove binaries folder) Regards, Prasad Hello Prasad, Thank you for you tips. I did "gmake -s clean" before build cmd, and the target works well.
