Hello,
I am new to working with microcontrollers & I am trying to write a boot up process for the TMS320F2838D.
I am experiencing an issue when I try to run boot up the CPU2 without the debugger connected.
When I debug my program. I see both cores enter their respective main loops.
When I load the firmware onto both of the CPU's start them with the debugger and than power cycle the processor I get no activity from CPU2.
The Tech. Ref. Manual states that the steps of booting CPU2 from CPU1 are...
-To configure the CPU1TOCPU2IPCBOOTMODE register which I attempt to with the value 0x5A00C803.
-To set the CPU1TOCPU2IPCFLG0 flag.
-Release CPU2 from being held in reset.
I've attached a snippet of my CPU1 program where I attempt to follow these steps.
As I mentioned earlier I am still becoming familiar with the devices so detailed explanations will be greatly appreciated.
Thank you in advance.
