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.
