AM1707 PSC Initialization

Other Parts Discussed in Thread: AM1707

Hi,

I try to connect Spectrum Digital AM1707 EVM to CCS v.4 using on board JTAG emulator.

When I connect to the device OnTargetConnect( ) GEL script is executed from evmam1707.gel Version 0.61.

The script fails on those lines:

Setup_Psc_All_On( ); // Setup All Power Domains

Enable_ARM();

it never goes out of the infinitive loop:

while( (*(unsigned int*)(PSC0_MDSTAT+4 * LPSC_num) & 0x1F) !=0x3);

while( (*(unsigned int*)(PSC1_MDSTAT+4 * LPSC_num) & 0x1F) !=0x3);

it looks like PSC0/PSC1 module does not set status bits.

If I ignore the errors, or comment out above lines the status of Device becoming - Connected.

I cam load the application to the target, but I cannot execute, or debug loaded application.

Is there any solution for this problem?

What is the reason for such failures?

Thanks.

Have you tried to merge the PSC initialization into your main() function before you try and execute the rest of your program.

You don't necessarily need to use the GEL file in order to initialize the PSCs.

The problem is sorted out.

I had to change boot mode switch SW2 from Default position to Emulation Debug position.

I assume that not correct switch settings affected PSC setup.

Anyway, everything is working fine - as expected.

Thank you.
