LP-AM243: Cannot find IP adress in 1-Gbps Full-Duplex mode

Hi,

Can you please let me know SDK version you are using?

Normally, we see 1Gbps not working due to timing/delay issues causing packet drops resulting in no IP. We had issue of packet drop in our earlier versions of SDK which is fixed in SDK8.1.

Hello Mr Prasad Jondhale.

I used: "mcu_plus_sdk_am243x_08_01_00_36" and "Code Composer Studio 11.1.0"

Can you sahe me SDK8.1 iss it here: "mcu_plus_sdk_am243x_08_01_00_36"??

thanks and best regards,

Hi,

The version you have has fix for the packet drop issue. Not sure why you are still seeing packet drop.

Can you please print the statistics and see anything unusual?

Hi Mr Prasad,

Today i checked print state as your recommend.

I receive 2 case test like below:

1. If  port status return nothing. I always can run terminal and see Cpsw handle like PIC below and don't return IP

2. If  ports return status info. I always see terminal console issue inform the same in all case test like that:

==========================
ENET LWIP App
==========================
Enabling clocks!
Starting lwIP, local interface IP is dhcp-enabled
CPSW_3G Test on MAIN NAVSS
EnetUdma_openRxCh: [Enet UDMA] UDMA RX Channel open failed: 0xffffffff
EnetHostPortDma_open: Failed to open Enet DMA RX channel: -1
Cpsw_openInternal: CPSW: Failed to open CPSW DMA
Cpsw_closeInternal: Assertion @ Line: 921 in /home/gtbldadm/nightlybuilds/repo_manifests/scripts/jenkins/mcu_plus_sdk_am243x_08_01_00_36/source/networking/enet/core/src/per/V1/cpsw.c: hCpsw->hRxRsvdFlow != NULL

And here is the PIC i capture:

Return Port 0 and port 1 info:

Only return port 1 info:

--> Could you please give me some suggestion to do next?

--> What different between ports return data and return no data?

--> What and where i need to do to fix IP address config(ex: 192.168.1.12) in gigabit mode? Because some time i received address: 192.168.1.12 in 100Mb mode. 

--> can you send me "enet_lwip_cpsw_am243x-lp_r5fss0-0_freertos_ti-arm-clang" example you test run well by email: duong.vu@intins.vn ?

thanks and best regards,

Hi Duong,

Below error tells that the sysfw image is not latest or consistent with what the SDK version is using.

EnetUdma_openRxCh: [Enet UDMA] UDMA RX Channel open failed: 0xffffffff
EnetHostPortDma_open: Failed to open Enet DMA RX channel: -1
Cpsw_openInternal: CPSW: Failed to open CPSW DMA

Are you using SBL NULL mode or using gels to configure SOC?

Can you please share your sysfw boot logs?

Regards,

Prasad

hello Mr Prasad,

(Your question): Are you using SBL NULL mode or using gels to configure SOC?

--> can you explain more. I am new member TI chipset, can you send me link to understand SBL NULL mode and gels to configure SOC?

If i understand SBL mode is default, right.

(Your question): Can you please share your sysfw boot logs?

--> where to get sysfw boot logs?

I have a question: when" enet_lwip_cpsw" example run in 100M mode it return IP 192.168.1.12.

So i can ping to 192.168.1.12. 

But if i turn off LP-243x power and turn on it again. I can not ping address 192.168.1.12?

Why and what happen mr Prasad?

Regards,

Hi Duong,

No issues. You can get more details about SBL NULL vs gel files approach of initializing the SOC.

AM243x MCU+ SDK: SBL NULL (ti.com)

AM243x MCU+ SDK: EVM Setup (ti.com)

Can you share your typical development flow? How do you load binary into R5F - via CCS or it's flashed.

Prasad
