Connection to F28069 Control Card Hung (again) when Trying to Launch Debug in Code Composer

Hi,

If you've programmed wrong password and want to remove it or unlock the chip, you'll have to reboot in Wait mode ie Mode 2. For this you'll have to configure your Boot pins according to the table. This config is done on hardware itself.

Hi,

As Gautam mentioned, you need to drive '1' on GPIO37 pin during boot to select the "Wait Boot" option and it need to be done on the hardware you have. I think confusion you are having due to the muxing of GPIO37 with TDO, which is JTAG pin. I would suggest to have a week pull-up on this pin instead of driving high and then follow following steps -

- Disconnect the JTAG pod

- Power-up the board again

- Attach the JTAG pod and then try to connect to CCS

Please refer section "6.9.14 JTAG Port" of datasheet for more detail on this muxing.

Hope this helps.
