Hello everyone, I am a student trying to program a small operating system on the DSP side of DM3730 (For experimenting and knowledge improving), and now met some problems of the boot address of DSP side.
I have found a copy of ucos for C6000 code, which I only made little change and then could successfully on DSP size of DM3730. I can build it in CCS, and monitor it's running status with CCS debugger.
From the TRM of DM3730, the reset address of DSP side is set by the ARM processor, so I cann't understand how ①what's the reset address when the DSP core is triggered by the CCS debugger? And I also have another question would like get help from you, ②ow can find the load address used by DSPLink to load DSPBIOS onto the DSP core? This would be important if I want to replace DSPBIOS with my own OS and let DSPLink load it.
And lastly, the .cmd file I used for DM3730 is downloaded from ti wiki, ③why we should list the ISRAM in the MEMORY area? Will the binary file be downloaded to ISRAM by the CCS debugger?
MEMORY
{
ISRAM: o = 0x40200000 l = 0x00010000 /* 64kB Internal SRAM */
CS0_SDRAM: o = 0x80000000 l = 0x20000000 /* 512MB of external mDDR in CS0 */
CS1_SDRAM: o = 0xA0000000 l = 0x20000000 /* 512MB of external mDDR in CS1 */
/* DM3730 EVM */
/*FLASH: o = 0x20000000 l = 0x10000000*/ /* 256MB of external NAND FLASH */
}
Thank you , any suggestion would be really appreciated !
The following is my .cmd file and .map file if you need to check it.
