问题: MSP430是否可以使用BSDL文件构建JTAG链?
描述: 所有 MSP430均具有仅用于程序开发与快闪编程的JTAG 接口。但这个JTAG接口并不完全与IEEE 1149.1兼容。例如,任何MSP430均没有边界扫描单元 (Boundary Scan Cell)。我们仅支持所需的命令 BYPASS,但不支持其它所需的命令:EXTEST 与 SAMPLE/PRELOAD。
结论: 任何 MSP430 器件都没有BSDL 文件。您不能将MSP430 与其它器件一起放入 JTAG 链中。
However this JTAG interface is not 100% IEEE 1149.1 (JTAG) compatible. For example none of the MSP430 devices has Boundary Scan Cells. We only support the required command BYPASS, but don’t support the other required commands for example EXTEST and SAMPLE/PRELOAD.
Therefore there is no BSDL file for any MSP430 devices. In addition you can not put a MSP430 into a JTAG chain together with other devices.
