IPC message copy to RAM involves copying application code from CPU1 IPC message RAM 1 to CPU2/CM destination RAM for execution. The maximum copy length size is 1000 words (2000 bytes) and the minimum is 100 words (200 bytes). Refer to Table 5-45 for details regarding configuration and execution flow of this boot mode.
Step | Action |
---|---|
1 | CPU1 application links CPU2/CM code to copy in either CPU1TOCPU2MSGRAM1 or CPU1TOCMMSGRAM1. |
2 | CPU1 application configures CPU2/CM IPCBOOTMODE with the copy length and IPC message copy as the boot mode. See Section 5.7.2.2 for more IPCBOOTMODE details. |
3 | Once CPU2/CM is released from reset to boot, CPU2/CM begins copying from CPU1TOCPU2MSGRAM1/CPU1TOCMMSGRAM1 to their destination RAM. Refer to Table 5-46 for destination RAM details. |
4 | Once the copying is complete, CPU2/CM boot branches to the entry address of the destination RAM and begins executing the application. |
CPU | RAM | Destination Address Range(1) (For maximum copy length of 1000 words) |
---|---|---|
CPU2 | M1RAM | 0x0000 0400 to 0x0000 07E6 |
CM | S0RAM | 0x2000 0800 to 0x2000 0FCC |
