    Hello, In order to perform Ethernet boot, I wish to program the i2c eeprom on my EVM with the secondary boot example instead of the IBL. When running the secondary boot in debug mode it works a sends the BOOTP package as expected. But when I use the make file supplied and program it to the eeprom...

    Greg, It looks like you are referencing the correct documentation, so you might find some example code helpful. The SYSBIOS MCSDK contains a simple example for configuring the Ethernet. If you haven't already downloaded the MCSDK, you can download it from this website: http://software-dl.ti...

    Hi all, I am working on TCI6618's bootloader using I2c and Ethernet. But I can NOT make out the correct boot parameter table of Ethernet boot. By reading the user guide of bootloader (2011 version), there are several parameters not found in the GbE user guide, such as SGMII Rx / Tx / Aux Cfg register...

    Yatsir, Are you trying to power down NetCP between runs to emulate some sort of power down state, or are you simply looking for a way to execute the example multiple times without having to power down the EVM? If it is the latter, then after executing the example code, then you should be able to do...

    Koray, It sounds like the power domain for the NetCP may not be getting turned on successfully. I have attached a GEL file that you can use to get the status of the Power Sleep Controller Registers. (Please visit the site to view this file) After you run your application and notice a failure...

    Koray, I am glad to hear that your setup is working now. Was 312.5 MHz clock that you were showing in the scope captures the input for the SGMII SerDes PLL? Did you make any other changes to your setup? Although the SGMII SerDes input clock could prevent the SGMII and SerDes interfaces from...

    Derek Brown
    Jochen, Can you please measure the frequency at the SYSCLKOUT pin (pin AE3). You can use test point 12 (TP12) on the EVM to measure this signal. This is the same DSP/6 clock that is used for MDIO input clock, and should be 166.67 MHz for 1 GHz CPU operation. Before measuring this pin, please make...

  • Forum Post: Re: Ethernet not working after link has been down

    Derek Brown
    Gertjan, It is unlikely that what you have described is the QMSS stall error. However, to avoid this issue, you should use internal linking RAM (recommended unless you need more than 16K descriptors) or put the descriptors and linking RAM in different locations. After the link comes back up, are...

    Gertjan, Since you are seeing the statistics update, then that means that the packets are getting into the Ethernet switch. Are the packets getting out of the Ethernet Switch? If you are not sure, then use can use the following procedure: After you encounter the issue, please halt your program...

    Gertjan, I am glad to hear that you were able to resolve this issue. From a hardware perspective, this bit does not need to be set if software is going to be setting up the speed and duplexity of the EMAC and SGMII modules. This bit only needs to be set if the EMAC needs to get the speed and duplexity...

    Jochen, Is your code enabling the EXT_EN bit in the MAC Control register? I found this post where someone was having trouble with the link when the EXT_EN bit was set, and the issue went away when the EXT_EN bit was cleared.

    Hi, PA LLD inside MCSDK supports Jumbo frames. You also have to configure P0_RX_MAXLEN, EMAC1 RX_MAXLEN and EMAC2 RX_MAXLEN registers in your application from switch sub-system to allow the jumbo frames to be received and sent out from switch sub-system. Regards, Bhavin
