File not found during U-Boot flash in Yocto Linux for ADSP-SC589 MINI

Hi Samy,

1. It seems there is some issue with your TFTP server setup. From the log shared I could see the severip set was "setenv serverip 172.21.3.123"

But later "TFTP from server 172.16.4.177" was used. 

2. It looks for the file "u-boot-sc589-mini.ldr" under your Windows location  "C:\Program Files\DesktopCentral_Server\osdPEMedia\P" 

Suggestion: 

1. Try copying the "u-boot-sc589-mini.ldr" file under "C:\Program Files\DesktopCentral_Server\osdPEMedia\P" in Windows location - ( I Recommend )

or

2. Need to fix your TFTP server configuration which should look into your Ubuntu machine /tftpboot directory.

Thanks,

Prasanth R

HI Prasanth, 

       Thanks for feedback. Please find our comments in below,

1. PC ip address is shown as '172.21.3.123', based on the ip address given in setenv serverip 

But when running 'run update' command, TFTP from server 172.16.4.177 is displayed. 

Please let us know whether ip address should be '172.21.3.123' when running 'run update' command. 

2. Windows OS is not installed & only Ubuntu 20.04 is installed. We are not clear why it is showing the windows location.

Regarding fix in tftp configuration we followed the below procedure, do we need to add any other point, please let us know

$ sudo vi /etc/default/tftpd-hpa

#Replace the existing file with the following
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"
#End of File

$ sudo mkdir /tftpboot
$ sudo chmod 777 /tftpboot
$ sudo service tftpd-hpa restart

We can view the 'u-boot-sc589-mini.ldr' file in '\tftpboot' folder. 

Hi Samy,

It seems you haven't configured your TFTP server well. Try the below setting which was used in my machine.

1. install the TFTP server and NFS server

```

# sudo apt-get install xinetd tftp tftpd isc-dhcp-server nfs-kernel-server portmap -y

```

2. On Ubuntu, edit /etc/xinetd.conf and add the following lines just above the line that reads includedir /etc/xinetd.d.

```
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
}
```

3. Create the /tftpboot folder if it does not exist:

```
# mkdir /tftpboot
```

4. Restart the xinetd server with the following command:
```
# /etc/init.d/xinetd restart

# ps -alxww | grep inet
140 0 578 1 0 0 1152 356 do_select S ? 0:00 xinetd ...
0 500 13361 13336 18 0 1360 508 pipe_read S ? 0:00 grep -i inet
```

5. Test the TFTP server with the following commands

```

# echo "Hello, embedded world" > /tftpboot/hello.txt"
# tftp localhost
tftp> get hello.txt
Received 23 bytes in 0.1 seconds
tftp> quit
```
```
# tftp localhost
tftp> get u-boot-sc589-mini.ldr
Received * bytes in 0.4 seconds
tftp> quit
```

tftp 0xc2000000 172.21.3.123:/tftpboot/u-boot-sc589-mini.ldr

Hi Prasanth,

I configured the TFTP server as you given in above steps.

I given 'tftp 0xc2000000 172.21.3.123:/tftpboot/u-boot-sc589-mini.ldr' in Flashing U-Boot to SPI Flash on TFTP. It is showing the "Loading: T T T..."

Please find the log in below. Kindly let us know your feedback.

Hi Prasanth,

We can able to flash the uboot loader now.. We given 'save' command after  setenv serverip. With this update, flashing is successful.

=> setenv serverip 172.21.3.123                                                 
=> save           

We will ask you further queries if any.

Regards,

Ramasamy S.

Hi Samy,

Glad to hear.

Thanks,

Hi Prasanth,

Thanks for support.

Further, I'm trying to run the SHARC LED blinking application loader created in windows & trying to invoke the application from Linux using following guide.

https://wiki.analog.com/resources/tools-software/linuxdsp/docs/linux-kernel-and-drivers/remoteproc/remoteproc

"blinky_Core1_sc589_mini.ldr " is kept in 'tftpboot' folder in linux pc for verification.

But i'm getting error as in below,

----------------------------------------------

root@adsp-sc589-mini:~# cd /                                                    
root@adsp-sc589-mini:/# echo -n \tftpboot > /sys/module/firmware_class/parameter

--------------------------------------------------

Please correct, am i missing anything here?

Hi samy,

is this blinky_Core1_sc589_mini.ldr really exist in the rfs? or only in /tftboot directory? 

copy blinky_Core1_sc589_mini.ldr file into your root filesystem location /lib/firmware/

Thanks,

Prasanth R

Dear Prasanth,

Sorry, I given local Linux PC path as '/tftboot.

Kindly let us know, how to copy linky_Core1_sc589_mini.ldr file root filesystem location /lib/firmware/

Please share the relevant document for this.

Hi Samy,

Could you let me know how the roots was mounted for your device?

If you were not aware share your bootargs from your uboot promot. #printenv bootargs

If you are using SD card, just do a sudo cp blinky_Core1_sc589_mini.ldr to the /lib/firmware 

If it's a nfs boot copy the file to your nfs mount location?

Thanks,

Prasanth R
