omap1510 dsp's reset vector table - garlord garlord - Feb 6 21:54:00 2005

i want to set omap1510's dsp reset vector table to arm side memory so i can use mailbox interrupt handler. (1) how to write the interrupt vector table. i write one like B _c_init_00 NOP .align 8 B _xxxxx NOP .align 8 that is right? (2)how to map the table above to 0xffff0,which in dsp pdrom space.i do the following i have successful made dsp mmu running. first enable dsp mmu and create tlb entry map the 0xfff000(dsp memory address) to 0x10200000(arm system memory address. then.write 0x0 to mpui boot config register to config dsp boot from emif last reset dsp. that is right? (3) how to make dsp reset from that reset vector ? before reset and unreset ,idle state is needed? |
