FAQ - General

Where can I find the console command reference and OMAP 35x EVM user guide document in the CD?

The console command reference documents and OMAP 35x EVM user guide documents are available within the OMAP35x_SDK_0_9_5.iso image. They are OMAP35x_SDK_0_9_5.iso\OMAP35xEVM_HW_User_guide.pdf and OMAP35x_SDK_0_9_5.iso\OMAP35xEVM_Getting_started.pdf

Are there any royalties to pay for products based on the kit?

No. There is no royalty pay for the EVM or for the use of the design in your own designs. In the future there will be additional components that may or may not include additional royalties.
Please contact omap@mistralsolutions.com if you are not sure.

Is the CSST tool supported by the OMAPEVM?

No. Please use the Download Utility that is provided to download the peripheral u-boot via the serial port.

Which JTAG Emulator can be used for the OMAP3EVM? Are there any jumper settings/switch settings for connecting the JTAG Emulator?

You can use the Spectrum Digital’s XDS510 or the BlackHawk’s USB 560m emulator along with the TI CCS ver 3.3. When you are trying to connect the OMAPEVM to the JTAG Emulator, please make sure that the OMAPEVM is in the JTAG mode. For this make the SW1-1 of the processor module ON. Refer to Table 30 of the Hardware User Guide for more information on this.
