在淘宝买 了个核心板，https://item.taobao.com/item.htm ... 0&_u=8bavat8eea下载时需要按着RESET不放，然后点下载，松开后即可成功下载。否则，无法下载成功。 Info : clock speed 4000 kHz Info : STLINK v2 JTAG v27 API v2 SWIM v6 VID 0x0483 PID 0x3748 Info : vid/pid are not identical: 0x0483/0x374B 0x0483/0x3748 Info : using stlink api v2 Info : Target voltage: 3.312064 Info : STM32F103C8Tx.cpu: hardware has 6 breakpoints, 4 watchpoints Error: timed out while waiting for target halted TARGET: STM32F103C8Tx.cpu - Not halted in procedure 'program' in procedure 'reset' called at file "embedded:startup.tcl", line 478 in procedure 'ocd_bouncer' ** Unable to reset target ** shutdown command invoked 如果按着RESET，点下载，然后再松开，则会有下面的提示过程： Info : clock speed 4000 kHz Info : STLINK v2 JTAG v27 API v2 SWIM v6 VID 0x0483 PID 0x3748 Info : vid/pid are not identical: 0x0483/0x374B 0x0483/0x3748 Info : using stlink api v2 Info : Target voltage: 3.312064 Info : STM32F103C8Tx.cpu: hardware has 6 breakpoints, 4 watchpoints STM32F103C8Tx.cpu: target state: halted target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0x08001058 msp: 0x20005000 ** Programming Started ** auto erase enabled Info : device id = 0x20036410 Info : flash size = 64kbytes STM32F103C8Tx.cpu: target state: halted target halted due to breakpoint, current mode: Thread xPSR: 0x61000000 pc: 0x2000003a msp: 0x20005000 wrote 5120 bytes from file Debug/c8t6spi.elf in 0.329144s (15.191 KiB/s) ** Programming Finished ** ** Verify Started ** STM32F103C8Tx.cpu: target state: halted target halted due to breakpoint, current mode: Thread xPSR: 0x61000000 pc: 0x2000002e msp: 0x20005000 verified 4432 bytes in 0.085779s (50.457 KiB/s) ** Verified OK ** shutdown command invoked |
如何通过ISP的方式下载呢？？？
这个板子是可以自己配置BOOT0/1的，我不太会配置这个跳线。请指点下
时钟速度太高了。ST的只支持到1.5M左右。降低试试
换个不是低功耗的程序烧录，应该就正常了。
