BSL programming through radio interface

Other Parts Discussed in Thread: CC2520, CC2500, MSP430F248

Hi everybody,

This is my first question in this forum, so I'd like to apologize in advance if this is not the right place to post it or if it turns out to be a silly question.

It has been some time now since I started working with the MSP430 MCU for my degree project. So far I have managed to program it through the bootstrap loader and then using the MSP-FET430.

I have developed my own platform that makes use of a CC2520 radio attached to the MSP430 SPI interface. I wish to know wether it is possible or not to program my own bsl routine so I could program the MSP430 through the radio interface. The idea is that it should work like this:

1.- load the code in some specific adress of the MSP430 flash through the radio.

2.- start up the bsl programming routine which should read the code from the flash to program the MSP430.

3.- reset the device.

Everything I have found regarding the MSP430 bootstrap loader refers to the UART interface, so I would appreciate so much any help about this.

Thanks in advance

Hello Luis,
please have a look on the Chronos Wiki. There is a section RF BSL, which should give you some ideas how to continue.

Regards,
Thomas

Hi Luis,

like Thomas told, that is exactly what Chronos RF BSL is based on.

There is a project that may help you.

Please go to this page http://focus.ti.com/docs/toolsw/folders/print/ez430-chronos.html
Download the actual software package(eZ430-Chronos Software Package (Rev. A) ).
Install the package. This will copy the source codes to your computer.
Check the "Wireless update" under C:\Program Files\Texas Instruments\eZ430-Chronos\Software Projects\Chronos Watch\IAR\Wireless Update

Best regards,

Patrick

Hello,

I know I am reviving an old thread here, but I am trying to do the same thing. Luis, did you, or anybody else for that matter, have any luck with this? I think I should be okay getting the RF-BSL onto my device (CC2500 and MSP430F248), however I am unsure of what needs to be done by the device sending the code (ie replacing the Chronos Control Center and the CC1111 USB access point).

Any help with anything that I should know would be much appreciated.

Thanks for your time,

Rhys H.
