Hello,
I'm playing with the new MSP432 Launchpad, and want to implement a Boot Override Flash Mailbox configuration to use the hardware invoked TI BSL. But when trying to read the contents of the Boot Override Flash Mailbox, I'm getting a lot of 0xFFFFFFFF's instead of the Mailbox Start 0x0116ACF6 for example. In the Datasheet is described, that this area is not protected. So possibly it has been deleted sometime. My first question is, if it has been designed for 'self-reconsturction', i.e. writing the Mailbox Start content on my own etc.?
Besides, I'm sure, that the BSL is erased either. Is there a possibility to get the the original BSL back into Flash?
And last but not least, I'm missing the preprocessor defines for the Boot Override Flash Mailbox in msp432p401r.h. I think there should be added something like it has been done for the TLV:
