Part Number: DRA821U
Other Parts Discussed in Thread: SYSBIOS

Hi 

in this doc:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/latest/exports/docs/ethfw/docs/user_guide/demo_ethfw_combined_top.html

There is a table like the below, may you tell us how to assign the IP for R5F code and A72 core for the EthFW and Virtual Net driver respectivily?

THanks.

BR Rio

Device IP address
PC 1 (Plex server) 192.168.1.202
J721E/J7200 Main R5F core (running EthFw) 192.168.1.203
PC 2 (Plex client) 192.168.1.204
J721E/J7200 A72 core (virtual net driver) 192.168.1.205
Default Gateway 192.168.1.1

    Hi,

    You can lookup the variable  enableStaticIP in the file ethfw/apps/app_remoteswitchcfg_server/mcu_2_0/ndk.cfg You will be able to set all IP parameters, once done. Compile with the command make ethfw_all BUILD_SOC_LIST=J7200 and copy the binary out/J7200/R5Ft/SYSBIOS/release/app_remoteswitchcfg_server_strip.xer5f to /lib/firmware/ethfw folder in rootfs partition of SD card.

    Once you boot with this, you can configure the A72 variables with usual linux ifconfig command.

    Regards

    Hi Roy:

    Thanks.

    BTW, according your saying, so, whenever we want to change the IP of the R5F, we need to rebuild/remake the binary/SD card?

    This is no user-friendly.

    Will TI BU develop another easy way for changing the R5F IP?

    If you want dynamic IP then you can use DHCP. For static IP, the idea is that IP doesn't change frequently so it's not run-time configurable. Unfortunately there is no plan to add such a support right now.
