Today, we got a Development Board, bv561evb, from Hefei Youshi technology. It consists of a basic board and a power board. It is very small and exquisite, and it looks like 10 cm x 7cm. Connect the 12 V power cord, connect to the serial port, open the Super Terminal, configure it to 115200-n-1, then connect the network cable, everything is ready! Turn on the power, the system has been written on the board boot, from the Super Terminal can see the following information: U-Boot-1.1.3-ADI-2006R1 (May 21 2007-11:22:42) Adi BF533/561 U-boot support by besovideo Co. ltdserial port initialized with baud rate = 115200cpu: adsp bf561 rev 0.3 Board: besovideo bf561 Board (http://www.besovideo.com) Clock: VCO: 330 MHz, core: 330 MHz, system: 66 mhzsdram memory map: 0x00000000-0x03ffffff (64 MIB) trcd: 3, TRP: 3, tras: 6, twr: 2, CAS latency: 3 (sclk cycles) Flash: 0x20000000-0x207fffff (16 MIB) device ID: 0x18 (type 'flinfo 'For information on sectors) in: serialout: serialerr: seriali2c: readyautobooting in 2 seconds, press "" To stop ## booting image at 20040000... image name: bfin uClinux kernel created: 11:14:41 UTC image type: Blackfin Linux kernel image (gzip compressed) data size: 1770801 bytes = 1.7 MB load addres S: 00001000 entry point: 00001000 verifying checksum...
