Problem booting Linux.

Former Member

I've gone through Chapter 6 of CTT (ug873) to integrate AXI CDMA with Zynq PS HP slave port. I'm aware that the guide is for ZC702 which has 1GB memory whereas Zedboard has 512MB memory.

I've successfully implemented the standalone application (baremetal application of section 6.2) and it works fine without any problem. But I'm having problem with the Linux OS example shown in section 6.3.

I generated FSBL and BOOT.bin by using SDK. Also, I used devicetree.dtb, u-boot.elf (to generate BOOT.bin), zImage and ramdisk8M.image.gz that come with ug873 user guide.

I then copied all the above files to the SD card and turned on Zedboard. But, there wasn't anything happened. There wasn't a single character printed on Tera Term. I guess Linux didn't boot at all.

My question is - do I have to change the devicetree.dtb in this case?

Thank you very much.

    Hi,
    I am facing issues using AXI CDMA on bare metal application. Could you please help me out?
    I have followed all the steps in chapter 6 of UG873.
    Further, I have changed HP0 and HP2 addresses to 0x1FA00000 and 0x1FB00000, which is within zedboard's DDR range.
    I am running the example file-
    C:Xilinx14.6ISE_DSEDKswXilinxProcessorIPLibdriversaxicdma_v2_03_aexamplesxaxicdma_example_simple_poll.c
    But if fails to trigger the DMA.
    Please tell me what am I missing.
    Which example are you running? can you share it?
