Other Parts Discussed in Thread: OMAP-L138
We changed dsp chip from TMS320C6748BZWT4 to TMS320C6748EZWTD4E , new chip is a secure part.
In TMS320C6748BZWT4, We have program 1 and program 2：
1. program 1 is a boot program, it load data from FLASH(address 64K) , the data is bin file of program 2 . and parse the data.
copy each section to RAM . get program2's entryPoint and jump to entryPoint to start program2 as below:
appEntry = (void (*)(void)) entryPoint;
(*appEntry)( );
2. program 1 is a APP program.
3. use AISGen tool to generate program 1 AIS bin file; use out2rprc tool to generate program 2 app bin file.
4. combine AIS bin file and app bin file in a file, 0-64K space is AIS bin file , and 64K- xxx is app bin file.
5. then burn the combined to flash, DSP start from SPI0 FLASH.
6. DSP works normally.
Now dsp chip is TMS320C6748EZWTD4E.
I did the following work:
1. use SecureHexAIS_OMAP-L138 tool to generate a secure AIS bin file;
2. use out2rprc tool to generate program 2 app bin file.
3. combine AIS bin file and app bin file and burn flash as above.
4. When start DSP, program 1 start normally, but program 2 can't start.
How should I do to make program 2 workinng?
