I have AN4286, but some of the details are vague or confusing. Is there any other source of information on the bootloader? I am working with SPI, and have most commands working, but there are still a few mysteries. Is there example code for communicating with the bootloader over SPI?

Not seen any, and haven't used the SPI connectivity. Used the USART methods a lot, and disassembled the ROMs.

Thanks, clive1. I've had to disassemble the bootloader ROM for the TMS320, but have not done so for the STM32. Do you happen to have any disassembly files around, or notes that you could share? I'm sure I could manage to disassembly the ROM myself, but if I can save time, I'd appreciate it.
