MSP430F5438A: BSL Delay Question

Steve Widener

Part Number: MSP430F5438A

In the bootloader user guide (slau319af) section 1.4 states “Minimum time delay before sending new characters after characters have been received from the MSP430 BSL: 1.2 ms”

 

Does this mean we need a 1.2ms delay between each byte sent to the MSP430 or does it mean after a complete packet is sent you should delay 1.2ms (or does it mean something else)?

    Hi Steve,

    You do not need the 1.2ms delay between each byte. It is specifying the time time you need to wait after receiving a packet from the MSP430 to the next command you write to it. So think of it as being required every time the target MSP430 is swapping from TX mode to RX mode.

    Let me know if you have any more questions. 

    Best Regards,
    Brandon Fisher
