STM32:connecting to cpu via connect under rest failed.

一、问题描述：

通过JLINK链接STM32F765BG调试，J-flash中connect时提示如下错误：

ERROR:STM32:connecting to cpu via connect under rest failed.

Bad JTAG communication：Write to IR：Expected 0x1，got 0x3 (TAP Command:10)@Off 0x5.

二、解决措施

Options–>Project settings–>Flash，FlashBank选择“Bank 0（Internal flash）”,“Disable flash bank”前打勾。

再次connect 提示 Connected successfully.

Program 时提示如下错误：

Selected Data（0x8010000 – 0x80579D3) does not fit into selected flash sectors.

重新取消“Disable flash bank”前打勾。

再次connect -Program提示  successfully.
