Juan, To start the bootstrap loader on the chip, you need to pull TCLK down, then release it, then pull it down again, and only then to set RESET go high.
On the telosb/tmote skys this is done using the ADG715 chip. When you invoke "make telosb install", it calls a program called msp430-bsl, which activates the bootstrap loader and downloads the program. This program has several options as to how to pull TCLK down. Run it directly with -h to see the options, and then try to run it directly on your binary file with options that don't use the i2c interface (the ADG715) but which use DTR and RTS directly. You definitely don't need an ADG715; it is mainly used to send signals to TCLK, and there are other ways to pull it down. Sivan On 6/21/07, Juan Antonio López Riquelme <[EMAIL PROTECTED]> wrote:
We have acquired a development board for an MSP430F1611 microprocessor from Olimex (www.olimex.com) and we would like to develop a serial program interface using a serial port to interconect this board with the Windows XP-cygwin-tinyOS2.x environment. We are using 2 ST3232 (RS-232 interface chips) to interconnect signals RX, TX, DTR and RTS comming from PC's serial port to MSP430 micro's RXD1, TXD1, TCK and RST pins respectevely. We have also connected the TXD1 pin to BSLTX pin and RXD1 pin to BSLRX pin When we try to program device using the command "make telosb install bls,0" where 0 refers to COM1 we get an error output about" no synchronization with bootstrap loader". We believe that maybe the problem is that we are not using the ADG715BRU chip presented in the original Telosb schematic and we don't understand very well the functionality of such component to chek this believe. we have looked for this chip in internet and only SMD package version is available. We would like to know if it exist any equivalent chip using DIP package. We would appreciate any aditional information to help us. Thanks.
