dear sir:

I have readed this link https://community.freescale.com/docs/DOC-95014

fsl's link description as blow:

Connected by 2*mini_PCIe to standard_PCIe adaptors, 2*PEX cable adaptors, and one PCIe cable.

my question is:

1,"mini_PCIe to standard_PCIe adaptors" is what? where can I got it?

2,"PEX cable adaptors" is what? where can I got it?

HI mingmin

you should by these two cards

PM2C V2.1 (PCI-E / Mini PCI-E adapter)

then manually solder sata cable between them

please read carefully 'How to make it"

i.MX6Q PCIe EP/RC Validation System

Best regards

but when I test send and receive data, result is fail. can you help me?

my test cmd:

EP side:

root@freescale /unit_tests$ ./memtool -32 01000000=deadbeaf

Writing 32-bit value 0xDEADBEAF to address 0x01000000

RC side:

root@freescale /unit_tests$ ./memtool -32 40000000 10
