MDK 5 用JTAG不能下载，怀疑flash download设置不对

我的芯片是STM32F103VC，flash是256K的，选项里只有512K的STM32F10x，没有256k，
会不会是因为这个原因，还是其它问题？
点击下载后提示
* JLink Info: STM32F1xxx: Can not attach to CPU. Trying connect under reset.
***JLink Error: TCK (pin 9) low, but should be high. Please check target hardware.
Error: Flash Download failed - Target DLL has been cancelled

再次点击下载后提示
* JLink Info: TotalIRLen = ?, IRPrint = 0x..FFFFFFFFFFFFFFFFFFFFFE11
* JLink Info: STM32F1xxx: Can not attach to CPU. Trying connect under reset.
* JLink Info: TotalIRLen = ?, IRPrint = 0x..FFFFFFFFFFFFFFFFFFFFFE11
Error: Flash Download failed - Target DLL has been cancelled

另外在jtag 设置，JTAG device chain 里显示空白，是没有检测到芯片吗？

刚刚试了sw模式可以正常下载程序，选的是512k的flash
