hi all, I wrote drivers for the onboard flash on tms5402 dsk. For block0 and block 1, Iam able to program and erase flash memory. but when i run my program to check for the protection of other blocks (2,3,....) my dsk is going out of control. I dont see any changes on the console and no test string is printed. also the settings of the dsk are getting changed for example i configured the SWWSR for 923f and the SWCR = 0x0001. after executing the code these values are getting changed. I am having some confusion regarding the extended mapping and the addresses generated. Any help regarding this from anybody would help me a lot. regards kishore |

Hi, My application size is more than 64KB. Because of this I need to span my code into pages. I am able to create new memory page using DSP/BIOS config tools. I am able to build and link the code by placing the code in newly created page. When I load , some it is not able to load to newly created page. With different configuration of link command, I am able to load also. But when I am debugging, PC is not going to proper page address. If some of you resolved these issues, please let me know the steps involved to resolve this problem. Regards, Ravi |
