AM2434: 关于pcie外设

Part Number:AM2434Other Parts Discussed in Thread:AM2432

你好:请问除了AM243Xx的Technical Reference Manual,还有没有其他关于PCIE的资料?

Shine:

请问还需要什么方面的资料?硬件设计?

,

HE HE:

我在做软件开发,还有没有关于AM2432的PCIE外设资源的介绍的资料?

请问,下面的inbound和outbound的地址应该怎么配置?

,

Shine:

inbound outbound地址转换可以参考上面的TRM文档12.2.2.4.7 PCIe Subsystem Address Translation。

另外,您可以网上搜索一下PCIe协议介绍便于理解。

,

HE HE:

对于EP设备的inbound,手册写 PCIe to AXI Address Translation。那么 target address是AXI Address吗? base address(0x7000_0000)是PCIe地址?

看到您已在e2e论坛上咨询产品线工程师,请关注帖子的回复。https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1240338/am2432-inbound-and-outbound

Shine:

抱歉回复晚了,请看下面e2e工程师的回复。Sorry for the delay in the response. Digging further on your question, the address space 0x70000000 is corresponding to MSRAM_256K0_RAM in the Table 2-1 of TRM. My understanding is that the ATU space is mapped to this RAM in the PCIe example you pointed out.  I believe this address can vary based on the implementation of the software. Please let me know if this answers your question.
