各位大咖,小弟在烧写28035 FLASH做了如下的测试:
1、使用TARGET Configuration中的test测试,JTAG succeed;
2、烧写程序,连接上仿真器,提示如下的错误信息:
C28xx: GEL Output:
Device Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output:
Device Calibration not complete, check if device is unlocked and recalibrate.C28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.
C28xx: File Loader: Memory write failed: Unknown error
C28xx: GEL: File: C:\Users\hellokitty\Desktop\28035\Debug\test.out: Load failed.
28035 JTAG原理图如下:
GPIO34引脚通过电阻上拉;
3、XRS复位引脚每隔一定时间周期性低电平一段时间;
麻烦大咖们指点下了
