这个我大意了。 crusadelee 发表于 2015-4-21 13:12 UNION FLOATTOBYTE{ STRUCT {   Uint16      BYTE3:8;     // 31:24    Uint16      BYTE2:8;     // 23:16    Uint16      BYTE1:8;     // 15:8    Uint16      BYTE0:8;     // 7:0         }BDATA； FLOAT FDATA;//FLOAT 是32位的前提下 } DATA;

发现JATG TCLK 的时钟500K只有200MV

This utility will load the program 'sd560v2u.out'. The library build date was 'May 30 2012'. The library build time was '23:17:26'. The library package version is '5.0.747.0'. The library component version is '35.34.40.0'. The controller does not use a programmable FPGA.

The value is '-181' (0xffffff4b). The title is 'SC_ERR_CTL_NO_TRG_CLOCK'. The explanation is: The controller has detected a dead JTAG clock. The user must turn-on or connect the JTAG clock for the target. [End]
