How to get feedback about processor configuration via RCW Hard-Coded for P3041? I need test PCIe interface, so I'm use RCW Hard-Coded on the following way:
cfg_rcw_src[0:4] Encoding | RCW Hard-Coded Configuration Options |
---|---|
1_0100 | Three (x2, x2, x4 PCI) Express at 2.5 GHz , 100-MHz ref clk, all agent mode; all cores in boot hold-off; dual 4-pin UARTs enabled; platform ratio of 8:1; core PLL ratio of 14:1 |
I've got the following questions:
1 - How do I test of PCIe interface?
2 - How do release cores?
3 - RCW Hard-Coded provide interface for get feedback about configuration?
Can anyone help me with suggestions of ways to PCIe self-test?
Thanks.
Hi,
To answer your third question:
Please use reset status register to get feedvack about the configuration, when Hard-Coded, it could also read back from the status registers.
For your second one:
Use Boot release register (DCFG_BRR) to release your cores from holdoff
