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 <out file Name> -e <EntryPint Address> -a -boot -bootorg SERIAL -map
<newmap file name> -romwidth 16 -o <hexfile name to be created>
 
 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.
