#144069 - RE: Reset circuit, Bootloader mode? Responding to: ???'s previous message |
The point of the tristate buffer is to allow a reset circuit to be connected to the Reset pin at the same time. Do you have one Thanks for the replies.. I don't have a reset circuit in the board. The output pin of buffer is connected to the RESET pin directly. What additional circuit should be used? whether Gopal did not upgrade to the newest V7 of the bootloader and then in some way switched it to the "always bootloader" mode... I think the NXP website features V5 of the bootloader. Do you have version 7? Where is the 'always bootloader' mode selected? How to select / deselect it? Thanks and Regards, |
