Hello, I am newbie to the C64x+ DSP in OMAP35x.
I got Linux & running on the ARM, and µC/OS-II running on the C64x+ DSP.
I want to access (read / write) the Mailbox from the DSP-side.
i try to configure and enable mmu,but still can not access the Mailbox
/* MMU configuration Port */
*(int*)0x5D000050 = 0x00000000;
*(int*)0x5D000058 = 0x5D00000C;
*(int*)0x5D00005C = 0x5D000140;
*(int*)0x5D000054 = 0x00000001;
/* L4 - 0x48000000 */
*(int*)0x5D000050 = 0x00000010;
*(int*)0x5D000058 = 0x4800000C;
*(int*)0x5D00005C = 0x48000140;
*(int*)0x5D000054 = 0x00000001;
/* Enable MMU */
*(int *)0x5D000044 |= 0x2;
How & what do I need to setup on the OMAP3530 to allow the DSP to talk to the Mailbox ?
Thanks,
/Chu.
