Information about the firmware inside Internet Radio (Conrad's renkforce IR 1)

Favorites

Prepare source playlist

Create comma separated playlist.csv CSV file following the format below:

Title,URL

Compile and run the binary

$ make
$ ./favlist

Compile native ARM binary

Commands below will compile native ARM binary and upload it into /tmp dir on internet radio device. This command requires gcc-arm-linux-gnueabi package (but it is recommended to use musl cross-compilers).

$ make arm
# or using musl
# CC_ARM=~/musl/bin/arm-linux-musleabi-gcc make arm
$ ./upload favlist_arm /tmp %SRC_IP% %DST_IP%

Following command will upload playlist.csv into /tmp dir on internet radio device.

$ ./upload playlist.csv /tmp %SRC_IP% %DST_IP%

Then you can run converter directly on internet radio through telnet:

$ telnet %DST_IP%
# cd /tmp
# ./favlist_arm

Upload generated playlist into device

Install python-pyftpdlib package to configure simple FTP server on your local PC.

And expect package to automate telnet routines.

Then run:

$ ./runftp

to run temporarily FTP server. And then:

$ ./upload myradio.cfg /flash %SRC_IP% %DST_IP%

to upload myradio.cfg from the current directory into your Internet Radio's /flash/ directory.

NOTE: Reboot the radio after uploading myradio.cfg file. There is no other way to apply new favorites list.

Download file from internet radio device into the current directory

$ ./download %remote_full_path% %SRC_IP% %DST_IP%

Reboot the device

$ ./reboot %DST_IP%
