But after entering the QNX system, use CPSW2g,it can work and appear the am0 in ifconfig.

But when I used CPSW9g , and used ifconfig,then,the system stopped responding。

    Sorry for the delay in response.

    Could you do a clean build after the modifications ? Was it working prior to modification ?

    Also, could you please migrate to latest release SDK 8.0 ?

    Thanks for your reply

    After our investigation of the problem, we finally located the problem as: IPC communication is blocked, and the reason is that tispl. bin corresponding to McU1_0 cannot work. When the SD card is used, EVM works and ping normally, but when the EMMC is used, the compiled QNX-tispl. bin cannot use the bootloader properly or enter the Uboot.

    I use SDKV7.3, V8.0 not tried yet.
