If you use this platform, you may run into issues. The following information is provided as a service, but is not meant to be an authoritative guide on the subject.</p><p>The complete BF533-EZKit manual is available on the <a href="http://www.analog.com/UploadedFiles/Associated_Docs/179226691ADSP_BF533_EZ_KIT_Lite_Manual_Rev_2.0.pdf" class="urlextern" title="http://www.analog.com/UploadedFiles/Associated_Docs/179226691ADSP_BF533_EZ_KIT_Lite_Manual_Rev_2.0.pdf" rel="nofollow">ADI Web site</a>. This section are select sections from that manual (copied with permission).</p><p>The EZ-KIT Lite has been designed to demonstrate the capabilities of the ADSP-BF533 Blackfin processor. The processor has IO voltage of 3.3V. The core voltage is derived from this 3.3v supply and uses the internal regulator of the processor. The core voltage and the core clock rate can be set on the fly by the processor. Refer to the Hardware Reference Manual for more information.</p><p>The default mode for the processor is flash boot. The JP1 and JP2 jumpers determine the boot mode of the processor. The table shows the available boot mode settings. By default, the processor boots from the on-board flash memory. Normally U-Boot expects both Jumpers to be installed. </p><table class="inline"> <tr> <th> JP1 (BMODE1) </th><th> JP2 (BMODE0) </th><th> Boot Mode </th> </tr> <tr> <td> Installed </td><td> Installed </td><td> 16-Bit External Memory </td> </tr> <tr> <td> Installed </td><td> Not installed </td><td> Flash Memory </td> </tr> <tr> <td> Not installed </td><td> Installed </td><td> Reserved </td> </tr> <tr> <td> Not installed </td><td> Not installed </td><td> SPI EEPROM </td> </tr></table><br /><p> The External Bus Interface Unit (EBIU) connects an external memory to the ADSP-BF533 device. It includes a 16-bit wide data bus, an address bus, and a control bus. Both 16-bit and 8-bit access are supported. On the EZ-KIT Lite, the EBI unit connects to SDRAM and flash memory. 64 <acronym title="Megabyte">MB</acronym> (32M x 16 bits) of SDRAM connect to the synchronous memory select 0 pin (~SMS0).
