Hi,
I am working on MSP430F5255 BSL for updating firmware from UART. I am just using the code example MSP430F5438A BSL code(UART/USB/I2C/Timer) available in slaa450c.pdf document and changed the same code to work with MSP430F5255. But I found the explanation for BSL core command framing in slau319I.pdf document and followed the same.
I just connected TXD and RXD pins to PC through the MAX3232 level shifter. And trying to give the commands to the controller, but it is not giving any response (or)error commands.
When I am trying to give the wrong commands like wrong header and length, it is responding with error commands. But when I am trying to give proper commands the code is not responding with any type of Command.
Please suggest if anything I am doing wrong. And I need the following clarifications & suggestions from you.
-What are the hardware connections required for this communication from PC to controller with UART for BSL update?(In documents I found that the RTS and CTS pins are required)
And finally, I am going to interface my MSP controller(MSP430F5255) to CC3200MOD for this firmware update through UART.
What are the IO's required for communicating CC3200 with MSP430F5255 for UART BSL?
Note: In my application I already having the UART communication(TXD & RXD) between CC3200 and MSP430F5255?
Please suggest the solution ASAP.
Thanks,
Vivek
