Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hello:

When I made the SD card(RTOS), in SD card path"/media/gwm/rootfs/usr/lib/opkg/alternatives" , how to generate ".fw" files(e.g. j7-main-r5f1_0-fw), what is the generated process like.

Looking forward to your reply.

    Hi,

    Which SDK version is this ? Are you referring to the FW binaries loaded by remoteproc driver.

    Regards

    Hi, 

    SDK 7.0, renamed from the source code after it has been built (use "make linux_fs_install_sd").

    Best regard,

    Hi Yonghui,

    The fw files such as

    targetfs/lib/firmware/j7-c66_0-fw -> /lib/firmware/pdk-ipc/ipc_echo_test_c66xdsp_1_release_strip.xe66
targetfs/lib/firmware/j7-c66_1-fw -> /lib/firmware/pdk-ipc/ipc_echo_test_c66xdsp_2_release_strip.xe66
targetfs/lib/firmware/j7-c71_0-fw -> /lib/firmware/pdk-ipc/ipc_echo_test_c7x_1_release_strip.xe71
targetfs/lib/firmware/j7-main-r5f0_0-fw -> /lib/firmware/app_remoteswitchcfg_server_pdk_mem_map_strip.xer5f
targetfs/lib/firmware/j7-main-r5f0_1-fw -> /lib/firmware/pdk-ipc/ipc_echo_test_mcu2_1_release_strip.xer5f
targetfs/lib/firmware/j7-main-r5f1_0-fw -> /lib/firmware/pdk-ipc/ipc_echo_test_mcu3_0_release_strip.xer5f
 .. and others

    are generated from the PSDKRA package, you can refer to the various "make options" to build the relevant binary. For example, the ipc_echo_test above will be generated from make ipc_echo_test from the PDK folder.

    Regards

    Hi  Karthik,

    Thank you for your help, and I have another question, where is the ipc_echo_test demo.

    Best regards,

    Yonghui,

    The ipc_echo_test is present under PSDKRA/pdk_*/packages/ti/drv/ipc/examples/echo_test
