我想通过SCI烧写程序,配置IO 口为SCI boot mode,GPIO18 为 3.3V,GPIO29为3.3V,GPIO34 为0.3V,
使用C2PROG V1.5 烧写程序,点击program ,目标板重新上电,显示如下所示:
CRC Info added at 0x003F6261: 0x6501 0xEF8C 0x0000
*** PLEASE RESET TARGET IN SCI BOOT-LOADER MODE ***
Connecting with target (autobaud)... failed (no response
过一会电流会增大,但GPIO18 电压会降至0.26V。
当在ccs下仿真调试时 SCI能和PC 机正常通信。
如果使用BOOT SCI 是否需要硬件设置或者其他项目需要设置?
非常感谢!
