Hi, 

My TC377 debug port is locked because of protection, I want to downloading a program to release this protection. I can set HWCFG to Bootstrap mode, and I know select BSL/ASC mode in Memtool, but I don't know how to set communication between TC377 and Memtool in Bootstrap mode.

Does Miniwiggler support CAN/LIN communication of Bootstrap mode? If not, what should I do? 

Best regards

Hi, I  made a quick guide how to use the BSL with UART, so basically you only need a COM port (RS232) and access to pins 14.0 and 14.1. 

check the attached document.

Hi, ugo_8a

Thank you for your reply. I am using a self-made board without UART, could you please tell me how to access to pins 14.0 and 14.1 via RS232? Is it like that?

Hello, if you have a RS232 transceiver in the target board , yes you can connect as you shown in the diagram. if you do not have a transceiver you need to use an adapter (UART to 5v/3.3) take a look at this adapter:
