SW9 switch №2 in datasheet. TMDSEVM6670L

Taras Kolesko

Hello again.

I've not found in the documentation registers section for SW9. In case if i need to change the statical/dynamical IP mode, which adress i should be looking for?

Hi,

SW9 is a 4-position DIP switch. The first position is used for enabling the PCI Express Subsystem within the DSP. The second position is undefined by hardware and available for application software use. The third and fourth positions are used by selecting the PLL sources for CORECLK and PASSCLK of the DSP. For more information refer section "3.3.5 SW9, DSP PCIE Enable / User Defined and DSP_DSPCLKSEL /

FPGA_PACLKSEL Switch Configuration" on C6670EVM technical reference manual document.

Also refer TMDXEVM6670L EVM Hardware Setup guide:

Thanks,

Hi,

SW9 switch the second position is undefined by hardware and available for application software use. In MCSDK HUA demo example use this input to select the static IP mode or DHCP mode. Ex: If user SW 1 = OFF position: static IP mode (default), SW 1 = ON position : client mode

For more information refer MCSDK HUA demo example code(hpdspua.c): C:\ti\mcsdk_2_01_02_06\demos\hua\src\

Hi Taras,
You have to use SW9:2 for IP select mode, if its ON position then its DHCP mode else STATIC IP mode..

The following API will read the SW9:2 switch and proceed the required initialization for NDK examples.

platform_get_switch_state(1)

You can refer to the C6678 EVM HW setup guide for reference.
