Hello all,
I got the same problem when trying to boot my DSP in Standard Serial(16 bit
mode) Boot.
I have connected the MSP430 to feed the SCLK, FS and BRx (Starting with bit #15
to bit#0) to the McBSP0 of our TMS320C54CST.
I can see first 5-6 words are going fine to DSP (like 0x10AA, 0x0018, ....) but
some how after around 1800uS the XF pin goes up, which I suspect cause of the
problem..
To generate the hex file I follow the command line:
hex500.exe -e -a -boot -bootorg SERIAL -map
-romwidth 16 -o
Now I am sending the content of this file over BRx line using bit bang
protocol.
Main queries for us are as per below:
1. Should XF go up after getting low, if yes then when?(if possible can I get
the precise time)
2. what should be the minimum and maximum BCLK frequency for standard serial
boot (16 bit mode).
3. Is it possible if I can get the timing diagram (for transfering data to DSP
to make serial boot).
Many Thanks in Advance,
Manish.
