pn7220 enter loopback mode for Emvco L1 test

[SeanHu]

I am using PN722x on my device, and I want to set nfc into loopback mode by issuing nci command from kernel driver.
Can you provide me the correct nci command that can set pn722x into loop back mode.

Hi Kai,

Yes, We followed the Quick start guide and issue the EMVCoAidlHalComplianceTest command, but the PN7220 does not enter loopback mode. That's why I was asking for the NCI command so that we can enter loopback mode manually.

Hello @SeanHu 

After finished NFC mw integration, and the device bring up, you can run the application
$./EMVCoAidlHalComplianceTest type ABF
PN7220 should enter EMVCo L1 .
