我自己按照官方提供原理图画的板子,一片焊上了所有器件,一片是最小系统(只有电源,晶振,RTST,SWCLK,SWDIO),全系统的曾经调试了一天,下载过几十次,后来就下载不了,问过GD官方技术支持,将BOOT0接高,下载过2、3次。后来(BT0接地)就一直显示“could not power up debug port”,接高后能与JLINK通讯,但还是不能下载,显示“Cannot setup Breakpoint at Address**JLink Warning: Could not read memory location 0x20000000 when trying to set soft RAM BP
Cannot setup Breakpoint at Address
Erase Failed!
Error: Flash Download failed - "Cortex-M3"
Flash Load finished at 18:27:38”
最小系统板也一样,能连接,不能下载(BOT0接地):
“* JLink Info: Found SWD-DP with ID 0x1BA01477
* JLink Info: Found Cortex-M3 r2p1, Little endian.
* JLink Info: FPUnit: 6 code (BP) slots and 2 literal slots
ROMTableAddr = 0xE00FF003
Error: Flash Download failed - Target DLL has been cancelled
Flash Load finished at 18:32:40
”
我已经搞了2、3天了,都快要崩溃了,求各路大侠积极救助
谢谢!!谢谢!!谢谢!!
