AM2634: DP83822 Phy interface with AM2634

Hi Rohal,

The FAQ was on SDK versions 10.00 and before, post that some file structures have changed.

For using a TI PHY with custom board, please follow these steps: 

1. In example.syscfg, Enet (CPSW) -> board config-> mark as custom board. Since this is a TI PHY, the driver is already available in this path: C:\ti\mcu_plus_sdk_am263x_10_02_00_13\source\board\ethphy\enet\rtos_drivers\src\dp83822.c

2. Refer the enet_custom_board_config.c file from the other example (C:\ti\mcu_plus_sdk_am263x_10_02_00_13\source\networking\enet\core\examples\enet_layer2_multi_channel\am263x-cc\r5fss0-0_freertos\enet_custom_board_config.c)

3. I do not have any reference code for the DP83822 PHY, the PHY does not support any extended configuration as of now.

Are you strapping the PHY config? The basic PHY init and binding will be done, just that additional config is not supported as of now.

Shaunak

Hi Shaunak,

I configure the dp86822 in existing nonRtos project and able to compile and run, it shows below debug messages

after doing this not able to ping these IPs - can you suggest any operation or how to debug 

SDK version - mcu_plus_sdk_am263x_09_02_00_56

Interface - RMII 

2. i flash same code in eval board also, after that eval board also not able to ping,

previously its was working for me for all the example codes

i re-install the SDK and CCS also and try to flash existing example with RGMII interface but it also not ping, debug logs isn't showing any error.

Hi Rohal,

Can you follow the steps to check packet statistics from CPSW and LwIP as mentioned here: 

LWIP_STATS: https://dev.ti.com/tirex/explore/content/am26x_academy_10_00_00_00/_build_am26x_academy_10_00_00_00/source/debug_guides/ethernet_debug_guide.html#lwip-stats

CPSW_STATS: https://dev.ti.com/tirex/explore/content/am26x_academy_10_00_00_00/_build_am26x_academy_10_00_00_00/source/debug_guides/ethernet_debug_guide.html#cpsw-stats

This will help us isolate if the issue is at PHY integration level, or with CPSW or with SW (LwIP/App)

Shaunak

Thanks Shaunak for reply and support,

I installed mcu_plus_sdk_am263x_10_02_00_13 and Sysconfig 1.23.1

but it giving icss interface for Ethernet but i need cpsw interface in RMII,

for that i import the icss given project and try to compile for cpsw interface on RMII, its compiled successfully but 

while running its showing error

EnetAppUtils_reduceCoreMacAllocation: Reduced Mac Address Allocation for CoreId:0 From 4 To 2
Assertion @ Line: 207 in ../app_cpwsconfighandler.c: : failed !!!

I took the reference for previous version of SDK for cpsw interface,

Adding project also please look into this, i think code is stuck just because of cpswCfg->dmaCfg parameters 

please suggest what's wrong with this icss_emac_lwip_am263x-cc_r5fss0-0_freertos_ti-arm-clang.tar

No Shaunak, 

no directory with the name of CPSW

can you share SDK link (which SDK i have to use for this example code)

ok, got it,  example path changed from previous version, now its in source folder
