For reasons unclear the "devmem" command (part of busybox) is missing from the centos7 userland image.
To install it, do this:

HI,
By default the bridges will only allow privileged accesses in Arria 10.  At
this time i am not aware of any way to adjust this from linux space, but it
is entirely configurable from a uboot prompt.

= Load FPGA from Linux =
== THIS DOES NOT WORK ==
from here: https://forum.rocketboards.org/t/load-fpga-rbf-from-device-tree-overlay-example/999/16
<pre>
Finally, I found a working solution:
load_rbf.dts:
/dts-v1/;
/plugin/;
/ {
fragment@0 {
target-path = "/soc/base-fpga-region";
#address-cells = <1>;
#size-cells = <1>;
overlay {
firmware-name = "de10_soc.rbf";
#address-cells = <1>;
#size-cells = <1>;
};
};
};
dtc -O dtb -o load_rbf.dtbo -b 0 -@ load_rbf.dts
Copy load_rbf.dtbo and de10_soc.rbf to /lib/firmware
mount -t configfs configfs /config
rmdir /config/device-tree/overlays/test
mkdir /config/device-tree/overlays/test
echo load_rbf.dtbo > /config/device-tree/overlays/test/path
The magic command is:
devmem 0xff800000 32 0x00000019
I really don’t know what this does. However, by looking at how the bridge is enabled in u-boot:
#bridge_enable_handoff=mw $fpgaintf ${fpgaintf_handoff}; go $fpga2sdram_apply; mw $fpga2sdram ${fpga2sdram_handoff}; mw $axibridge ${axibridge_handoff}; mw $l3remap ${l3remap_handoff}
#mw $fpgaintf ${fpgaintf_handoff};
#fpgaintf=ffd08028
#fpgaintf_handoff=0x00000000
->devmem 0xffd08028 32 0x00000000
#go $fpga2sdram_apply;
->??
#mw $fpga2sdram ${fpga2sdram_handoff};
#fpga2sdram=ffc25080
#fpga2sdram_handoff=0x00000000
->devmem 0xffc25080 32 0x00000000
#mw $axibridge ${axibridge_handoff};
#axibridge=ffd0501c
#axibridge_handoff=0x00000000
->devmem 0xffd0501c 32 0x00000000
#mw $l3remap ${l3remap_handoff}
#l3remap=ff800000
#l3remap_handoff=0x00000019
->devmem 0xff800000 32 0x00000019
I found that this register needs to be written to 0x19 and then there is no bus error any more.

from here: https://forum.rocketboards.org/t/rbf-with-overlay/1800

Hi, this issue is resolved by adding following change in

compatible = “fpga-region”;
fpga-mgr = <&fpgamgr0>;
fpga-bridges = <&fpga_bridge0>;

Serial console

DE10-Nano has a built-in USB-serial adapter connected to the ARM CPU console.

Baud rate: 115200 (set in uboot env and in the linux kernel command line)

  • connect a mini-USB (*not* Micto-USB!) cable from mini-USB port on the side of the ethernet connection to a PC
  • "lsusb" will find a usb-serial adapter:
$ lsusb
...
Bus 001 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC
...
  • linux will create a ttyUSB device (see system messages if it did not happen)
$ ls -l /dev/ttyUSB*
crw-rw-rw- 1 root dialout 188, 0 Aug  8 17:12 /dev/ttyUSB0

minicom -D /dev/ttyUSB0 -b 115200

JTAG

DE10-Nano has a built-in USB blaster.

  • connect Mini-USB (*not* Micro-USB!) on the side of HDMI and power connectors to a PC
  • lsusb will show an altera usb-blaster device:
$ lsusb 
...
Bus 001 Device 008: ID 09fb:6010 Altera 
...
  • jtagconfig will find a usb-blaster and detect it is connected to a Cyclone5 SoC:
$ /daq/daqshare/olchansk/altera/17.1/quartus/bin/jtagconfig
1) DE-SoC [1-1.1]
  4BA00477   SOCVHPS
  02D020DD   5CSEBA6(.|ES)/5CSEMA6/..
  • open quartus, connect to this usb blaster, work it as usual.

Download DE10-Nano_v.1.3.1_HWrevC_SystemCD.zip, unzip, go into Demonstrations/SoC_FPGA, copy DE10_NANO_SoC_GHRD and HPS_FPGA_LED.

Together, they demonstrate how to flash the LEDs from the ARM CPU through the AXI bridge into the FPGA, into the qsys fabric into the PIO controller into the LEDs.

Board orientation is:

u-boot environment access from linux

  • on chronobox cb02 Raspbian-10
  • apt install cmake libyaml-dev
  • mkdir ~/git; cd ~/git
  • git clone https://github.com/sbabic/libubootenv
  • cd libubootenv
  • mkdir build; cd build; cmake ..; make; ls -l ./src/fw_printenv

use fw_printenv from above 

/dev/mmcblk0		0x200		0x1000
  • fw_printenv should work (it should NOT print "Warning: Bad CRC, using default environment" as the very first line)

Example: set MAC address from Linux: 

fw_setenv ethaddr 02:aa:bb:cc:dd:01
fw_printenv | grep ethaddr=

Install busybox

For reasons unclear the "devmem" command (part of busybox) is missing from the centos7 userland image. To install it, do this: 

wget https://busybox.net/downloads/binaries/1.28.1-defconfig-multiarch/busybox-armv7r
file busybox-armv7r 
chmod a+x ./busybox-armv7r 
./busybox-armv7r 
./busybox-armv7r devmem

FPGA bridge access magic

special magic may be needed to enabled /dev/mem access to the FPGA bridge, per https://lists.rocketboards.org/pipermail/rfi/2015-August/003259.html 

HI,

By default the bridges will only allow privileged accesses in Arria 10.  At
this time i am not aware of any way to adjust this from linux space, but it
is entirely configurable from a uboot prompt.

the above could easily be added to a uboot script and run automatically at
boot.

In linux, you can then

Load FPGA from Linux

THIS DOES NOT WORK

from here: https://forum.rocketboards.org/t/load-fpga-rbf-from-device-tree-overlay-example/999/16 

Finally, I found a working solution:

load_rbf.dts:

/dts-v1/;
/plugin/;
/ {
fragment@0 {
target-path = "/soc/base-fpga-region";
#address-cells = <1>;
#size-cells = <1>;
overlay {
firmware-name = "de10_soc.rbf";
#address-cells = <1>;
#size-cells = <1>;
};
};
};

dtc -O dtb -o load_rbf.dtbo -b 0 -@ load_rbf.dts

Copy load_rbf.dtbo and de10_soc.rbf to /lib/firmware

mount -t configfs configfs /config
rmdir /config/device-tree/overlays/test
mkdir /config/device-tree/overlays/test
echo load_rbf.dtbo > /config/device-tree/overlays/test/path

The magic command is:
devmem 0xff800000 32 0x00000019

I really don’t know what this does. However, by looking at how the bridge is enabled in u-boot:

#bridge_enable_handoff=mw $fpgaintf ${fpgaintf_handoff}; go $fpga2sdram_apply; mw $fpga2sdram ${fpga2sdram_handoff}; mw $axibridge ${axibridge_handoff}; mw $l3remap ${l3remap_handoff}

#mw $fpgaintf ${fpgaintf_handoff};
#fpgaintf=ffd08028
#fpgaintf_handoff=0x00000000
->devmem 0xffd08028 32 0x00000000

#go $fpga2sdram_apply;
->??

#mw $fpga2sdram ${fpga2sdram_handoff};
#fpga2sdram=ffc25080
#fpga2sdram_handoff=0x00000000
->devmem 0xffc25080 32 0x00000000

#mw $axibridge ${axibridge_handoff};
#axibridge=ffd0501c
#axibridge_handoff=0x00000000
->devmem 0xffd0501c 32 0x00000000

#mw $l3remap ${l3remap_handoff}
#l3remap=ff800000
#l3remap_handoff=0x00000019
->devmem 0xff800000 32 0x00000019

I found that this register needs to be written to 0x19 and then there is no bus error any more.



How to load RBF file from Linux kernel 4.1 on DE10-Nano SoC
