009-TFTP_Flashing.sh: Reflash the DF and NF using firmware in TFTP directory.

You can find a thoroughly of the tests in the header of each test.

Setup

# You need to setup a DHCP+TFTP server on your PC. In some distribution, you can use the package dnsmasq to ease the instalation (tutorial)

# Then you need to setup a NFS server in /tftpboot.

# You need to compile binaries from the lastest branch of wrs-switch-sw. Below a small exemple on how to look it but you should look at the official documentation

wr-switch-sw/build/wrs_build-all   
wr-switch-sw/build/wrs_build-all --pack

# You need to put in the TFTP's root directory (/tftpboot) the firmware you want to flash at the end of the test by copying

cp ${WRS_OUTPUT_DIR}/images/at91bootstrap.bin /tftpboot
cp ${WRS_OUTPUT_DIR}/images/barebox.bin /tftpboot
cp ${WRS_OUTPUT_DIR}/images/zImage /tftpboot
cp ${WRS_OUTPUT_DIR}/images/wrs-image.jffs2.img /tftpboot

# Then you need to extract the filesystem on your /tftpboot directory.

mkdir -p /tftpboot/rootfs-test
sudo tar -xzf ${WRS_OUTPUT_DIR}/images/wrs-image.tar.gz -C /tftpboot/rootfs-test

# And finally use the install scripts to send the files to tftpboot

sudo wr-switch-testing/sw/install.sh /tftpboot/rootfs-test/

Flashing

Once the compilation is done, you need to check the DDR and install the bootloaders into the dataflash for each board to test. Do do this you need to connect the left-USB port to your machine and execute:

wr-switch-sw/build/flash-wrs -c --build

Read the wrs-build doc to understand how to flash the board

Usage

Once the board is flashed, boot your board by pressing reset button. Connect to USB serial (Test)

minicom -D /dev/ttyUSB0 -b 115200

and select

boot from nfs (test)

during barebox menu. Then if everything go well (DHCP, TFTP & NFS) you should obtain the following message:

Starting up Test...

We do not recommend to run alpha-pts from serial port, because it is shared with FPGA UART.
To call the test you should try:

* USB Gadget:

minicom -D /dev/ttyACM0 -b 115200

* SSH:

ssh root@192.168.7.51

And then execute the testing script

/alpha-pts/testing.sh

This message show the basic steps to follow that are:

Open a USB Gadget connexion (left USB port)
Run /alpha-pts/testing.sh
Enter the serial of the board.
Wait until all the test are completed
Look at the log in your /tftpboot/rootfs-test/alpha-pts/logs/

Below, a log of a test with failing NAND (test 007) on sub test 0 & sub test 1:

   Thu Jan  1 00:00:41 UTC 1970

        001 > OK (00'06)
        002 > OK (00'00)
        005 > OK (00'53)
        006 > OK (06'34)
        007 > ERROR ( Sub0:13% Sub1:75% Sub2:OK Sub3:OK) (08'21)
        008 > OK (06'29)
        009 > OK (00'30)
        010 > OK (09'16)

You can also find a full log for each test andf one that keep an history of all test execution with the following nomenclatures

output-<SN>_<TESTID>.log
output-<SN>_history.log

Single test

Finally. by executing /alpha-pts/testing.sh --help you can obtain an help message where you can find out that test can be run separetly.

/alpha-pts/testing.sh [OPTION]... [TESTNUM]

Testing script to check various components of the White Rabbit Switch if TESTNUM is not defined all tests will be executed in ascending order

    Options:
        -h|--help           Show this little message
        -f|--force          Do not ask to continue
        -u|--update         Update binary files
        -i|--inlog          Create an independant log file for each test
        -l|--list           List the different building steps
        -s|--serial         Serial number

For example by calling

/alpha-pts/testing.sh -s 310010 -f 07

you will run test 007 (NAND) on board with S/N=310010 without prompting user if he wants to run it or skip it.

Troubleshoots

NAND*
It seems that the NAND test does not performs well on every board when it reach the address 0x08040000

Checking Block: 1026 @ 0x08040000 ............ERROR (26 %)

There is also an error when we try to erase a bad block, it is why we only use flash_eraseall -j to erase NAND flash at the beginning of the test.

Dataflash*

In case the dataflash is failling you can load the bootloaders directly to the ddr by using the following command:

wr-switch-sw/build/flash-wrs --test
