TMS320F28388D: Any solution to boot CPU1, CPU2 and CM via SCI ?

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Hello
after TMS320F28388D CPU1 boots via SCI, can I keep using SCI also to boot CPU2 ?
It's easily doable for 28377D since CPU2 supports SCI boot mode.
But it seems not easy for 28388D since CPU2 doesn't support SCI boot mode.
Is there any workaround ? 
Please kindly advise.
Thanks !

    Hello

    CPU1 SCI boot is only applicable to CPU1. A few options:

    • Store your own CPU2 SCI bootloader (can refer to the CPU1 SCI bootloader code in C2000Ware) in CPU2 flash or user OTP. Then CPU1 app will release CPU2 to boot to flash or user OTP which will then run the SCI bootloader
    • Use the CPU2 IPC Message Copy to RAM boot mode. CPU1 will store the CPU2 SCI bootloader code in the IPC message RAM, upon CPU2 boot, CPU2 copies this code to RAM and executes it

    Best regards
