JTAG linux boot with FPGA design

Hi

The ps7_init.tcl definitely does not clear the hardware in the PL.  You seem to be missing a few commands (which you may have left out):

"init_user" between step 5 and 6
"target 64" between steps 6 and 7
"dow -data ramdisk8M.image.gz 0x800000" between steps 11 and 12

Matthew

Hi Matthew,

Yes. "target 64" should be there between steps 6 and 7.
Sorry..Missed it on the forum post.

For the ramdisk8M.image.gz, I have separate file system partition on my SD Card which is pointed to by zImage and the device tree file, therefore I think it's not required.

Is the init_user same ps7_init?  I followed the ZedBoard_CTT pdf guide on the following zip file http://www.zedboard.org/sites/default/files/design/ZedBoard_CTT_v14.3_121017.zip. Section 5.2.3..

Hi again

No init_user is not the same, ps7_init initialises the processing system whereas init_user "enables level shifters between PS and PL and clears fabric port resets" (see UG873 section 5.2.2).  If Linux still isn't booting could you post the UART output.

Thanks.
Yes. That was the missing part to fix GPIO issue.

Now but at some point the OS bootup still crashes using this Jtag boot. It seems to be not loading the device tree. Though the CONFIG_XILINX_FIXED_DEVTREE_ADDR=y is set in kernel defconfig.

The UART output with errors for Jtag boot is as follows.

All the devices from this line "xusbps-ehci xusbps-ehci.0: Xilinx PS USB EHCI Host Controller" are not found in the Jtag boot output. Any ideas?

BTW: Here are steps I followed to fix above first issue.
connect arm hw
source ps7_init.tcl
ps7_init
init_user
source stub.tcl
target 64
fpga -f system.bit
dow u-boot.elf
con
pause uboot in terminal
stop in xmd
dow -data zImage 0x8000
dow -data devicetree.dtb 0x1000000

Attn admin: There is missing step in the Zed CTT guide. "init_user step when programming FPGA part to the PL"

Have you tried the same process with the pre-built Digilent Linux kernel?  There may be a problem with your zImage.

Matthew

Thanks.. I managed to Jtag boot with FPGA loading and linux.. it could be something with boot_args..Anyway thanks. I have jtag boot option now :)

Hi Matthew,

I get the following error when I am trying to download the u-boot image to the PL. I use the ps7_init.tcl from helloWorld example to init the first processor:
Download Progress.ERROR: Failed to download ELF file
tCannot access DDR: the controller is held in reset

Any clue?

Thanks

Hi

Could you list the commands you are currently using?  If the DDR is held in reset it is likely that you have missed a step.  Considering that the "init_user" command is supposed to clear fabric resets it could be that.

Matthew

Thanks, Matthew.

I followed the instruction in the documentation ZedBoard_VTT_v14.3_121017.pdf:
1. connect arm hw
2. source ps7_init.tcl (I used the file generated from HelloWorld example).
3. source stub.tcl (download from ZedBoard.org)
4. target 64
5. dow u-boot.elf. (it is this stage that gives me the error).

I do not see the init_user command in the documentation.

xiao

For some reason it isn't in the Zedboard CTT, but it is included in Xilinx's document (UG873).  The full set of commands are as follows:

xmd
connect arm hw
fpga -f system.bit
source ps7_init.tcl
ps7_init
init_user
source stub.tcl
target 64
dow u-boot.elf
con
< pause uboot in terminal >
stop
dow -data zImage 0x8000
dow -data ramdisk8M.image.gz 0x800000
dow -data devicetree 0x1000000

That should solve your problems
Matthew
