I also love TBDML because I started learning from MC9S12XD256. A while ago, I suddenly wanted to try making a TBDML, so I used TBDML_JB16-SOIC28 [Minimal]. pdf to complete the hardware. But I tested all the firmware and couldn't correctly install the drivers inside the sub folder of the USBDM_JB16-Distribution folder. I was planning to modify the VID&PID (modification date 12062008) corresponding to the driver in TBDML_JB16.abs.19, but I foolishly used ICP mode to upgrade USBDL_CF_JMxx ABS S19, from now on, JB16-PIN27 grounding can no longer activate ICP mode. I think it was based on MCU's s19 file that different ICP rewritten ICP's own Flash code space code? Can't ICP protect its own code space? This is a very magical process, and I am preparing to replace a JB16 to verify again. At the same time, I also want to know which driver (winXP) or win7 environment was used in the original TBDML. I am really confused! Thank you for maintaining these massive codes!
