How to start the receiver in sdr_receiver_hpsdr_122_88 mode? #1054

Closed w3ua closed 2 years ago

w3ua commented 2 years ago

Description of the setup:

Description of the problem:

I copied start.sh file to the root directory of SD card, as prescribed. But every time I boot the receiver, it starts in app selection state, so to start using it as a skimmer server, I need manually open http://xx.xx.xx.xx (my RP ethernet interface) and select SDR Receiver HPSDR 122-88 from the menu. Only then my Skimmer servers discover the receiver.

Ideal solution would be to create the single-use distribution (with no other apps but HPSDR receiver) and make it work from the beginning -- unfortunately, my skills with embedded linux preclude me from doing that. Any help will be appreciated

Steps to reproduce the problem:

  1. Install the SD image
  2. copy start.sh to the root
  3. boot.

I think you must be copying the HPSDR start.sh file to the wrong directory. It has to go to the /media/mmcblk0p1 directory. It certainly works on my system.

I agree with the previous comment. Looks like start.sh was copied to the wrong directory. The file should be copied to the topmost directory of the SD card. This directory contains boot.bin, devicetree.dtb, uEnv.txt, uImage.

I had single-use distributions in the past, but with the growing number of apps, it became difficult to maintain them. So I plan to keep the current system for a while.

Putting file start.sh to the root directory of FAT32 filesystem in the primary partition of the SD card created it in the directory @davidhay45 mentioned:

-----------------------------------------------------------------------------------------------
rp-f07bc5:/media/mmcblk0p1# ls

So the start.sh is definitely there -- but it doesn't work for me. Every tome I reboot my RP, I sill need to go to the RP URL and start the receiver app manually. What's wrong? Thank you.

Check that the start.sh has the execute attribute. This is what my start.sh contains:

rp-f099d6:~# cat /media/mmcblk0p1/start.sh
#! /bin/sh

apps_dir=/media/mmcblk0p1/apps

source $apps_dir/stop.sh

cat $apps_dir/sdr_transceiver_hpsdr_122_88/sdr_transceiver_hpsdr_122_88.bit > /dev/xdevcfg

$apps_dir/sdr_transceiver_hpsdr_122_88/sdr-transceiver-hpsdr 1 2 2 2 1 2 &

start.sh is definitely executable:

I have just tried to reproduce the problem.

I have formatted an SD card, unpacked red-pitaya-alpine-3.14-armv7-20220322.zip and copied start.sh from apps/sdr_receiver_hpsdr_122_88 to the topmost directory of the SD card:

# cp apps/sdr_receiver_hpsdr_122_88/start.sh .
# ls -l 
total 30224
drwxr-xr-x 29 root root    16384 Mar 22 21:36 apps
-rwxr-xr-x  1 root root   530336 Mar 22 19:10 boot.bin
drwxr-xr-x  2 root root    16384 Mar 22 21:36 cache
-rwxr-xr-x  1 root root    12497 Mar 22 19:18 devicetree.dtb
-rwxr-xr-x  1 root root 22048768 Mar 22 21:31 modloop
-rwxr-xr-x  1 root root     9162 Mar 22 21:36 red-pitaya.apkovl.tar.gz
-rwxr-xr-x  1 root root      594 Aug  4 12:21 start.sh
-rwxr-xr-x  1 root root      506 Oct 28  2021 uEnv.txt
-rwxr-xr-x  1 root root  5224368 Mar 22 19:18 uImage
-rwxr-xr-x  1 root root  3008195 Mar 22 21:31 uInitrd
drwxr-xr-x  2 root root    16384 Mar 22 21:36 wifi

When I boot Red Pitaya STEMlab 122.88-16 SDR with this SD card, the sdr_receiver_hpsdr_122_88 application starts automatically and I see two sdr-receiver-hpsdr processes running:

# ps aux | grep sdr
 2209 root      0:00 /media/mmcblk0p1/apps/sdr_receiver_hpsdr_122_88/sdr-receiver-hpsdr eth0 1 1 1 1 1 1 1 1
 2210 root      0:00 /media/mmcblk0p1/apps/sdr_receiver_hpsdr_122_88/sdr-receiver-hpsdr mvl0 1 1 1 1 1 1 1 1

So, for me, everything works without problems.
