[FAQ] MCU-PLUS-SDK-AM243X: How do I get CPSW diagnostic statistics using debug gels in MCU+ SDK Enet LLD?

CPSW statistics can be printed using below steps -

1) Launch CCS and connect to Main R5F0_0 core

2) Click on Tools --> Gel Files option from the top level menu

3) In the newly opened GEL Files window, right click and choose “Load GEL”

4) Choose file mcu_plus_sdk_xx_xx_xx\source\networking\enet\core\tools\debug_gels\cpsw_startup.gel.

Note - Please make sure to remove all existing gels before loading the startup gel.

5) Click on Scripts --> CPSW Statistics Print --> cpsw_xg_ststsprint_nonzero and you will see the stats registers on the console of CCS. 

Please make sure to half the CPU to run the gel file.

Below is device - gel mapping -

* cpsw2g - am273x

* cpsw3g - am263x/am24x
