dm368 vpfe接口问题



你好,目前采用开发包:IPNC5.1,前端是FPGA发送RAW模拟数据到DM368,数据是累加数,但是DM368接收的RAW数据是错误的,数据中有很多0,

我用的是moduletest drv_isif测试程序,寄存器打印如下:

0x01c71000: 00000003
0x01c71004: 00000000
0x01c71008: 00000000
0x01c7100c: 00000000
0x01c71010: 00000000
0x01c71014: 00000001
0x01c71018: 00000008
0x01c7101c: 00000287
0x01c71020: 00000004
0x01c71024: 00000004
0x01c71028: 000001e3
0x01c7102c: 0000ffff
0x01c71030: 000000ff
0x01c71034: 00000029
0x01c71038: 00000000
0x01c7103c: 00000418
0x01c71040: 0000e580
0x01c71044: 00000000
0x01c71048: 00000000
0x01c7104c: 0000e4e4

FPGA发送8位数据,我接的是DM368的C0~C7,CSL_CCDC_MSB_POSITION_BIT7
