3.2 Example – Disable PA18 BSL Invoke Pin With Sysconfig

The NON-MAIN configuration can be done with Sysconfig. Here is an example how to disable PA18 BSL invoke function in NON-MAIN flash, for PA18 is used for BSL invoke by default settings in NON-MAIN. If the application do not use the PA18 as the BSL invoke, this pin must be pull down or disable the BSL invoke function in NON-MAIN to avoid the device to into BSL mode when power up or reset.

  1. Open Sysconfig and add configuration NVM, this displays an error when you do this to remind you the risks to enable the NON-MAIN flash. Accept configuration risks at step 2 can remove the error.

  2. Disable the PA18 BSL invoke function show in Figure 3-2 or choose another BSL invoke pin show in Figure 3-3.

  3. Build the project in Code Composer Studio™ (CCS) or IAR or Keil and then download the code into flash. The important thing to download the image is to enable NON-MAIN flash erase. For example in CCS to enable this in Figure 3-4.
