Help needed with YS1 on raspberry pi 4

[bking46]

Hi All,
I am in dear need of help with the following issue I have encountered with rfcat on the raspberry pi with the yard stick one. My OS is Raspbian Buster, firmware rev on YS1 is 0348/x00 and bootloader is CC Bootloader

1.Executing print(d.reprRadioConfig()) in rfcat -r:
This outputs compiler not found, update needed.
Entered d.bootloader(), all leds on the ys1 lit up suggesting this is working. In addition I see the following line
"RESETUP set from recv thread"
2. In a separate terminal window I navigate to the location where the firmware folder is saved and issue make installRfCatYS1CCBootloader however this outputs error please see attached picture

SDCC is v3.8.0. I don't know how to install 3.5.0 since this could not be found in the repository.

Could you kindly help me get the ys1 to receive and transmit? Is the error I am getting due to the SDCC version? If yes, could you kindly guide me on how I can install the 3.5.0 version on Raspbian Buster ? What do I need to do to get rid of the "compiler not found, update needed message"?

Thank you for your help and patience!

in the latest releases, there are firmware builds you can use to update your dongle. i'm not sure how to get SDCC v3.5.0 on Raspbian. i do my builds on Ubuntu, and i have to include older versions (bionic) to get SDCCv3.5.0. i haven't figured out why yet, but >v3.5.0 creates firmware that don't work in any meaningful way.

if you download the firmware from the release (https://github.com/atlas0fd00m/rfcat/releases/download/v1.9.5/RfCatYS1CCBootloader-201231.hex), you should be able to update the firmware as follows:

$ rfcat --bootloader --force -S 
$ rfcat_bootloader /dev/RFCAT_BL_YS1 erase_all
$ rfcat_bootloader /dev/RFCAT_BL_YS1 download RfCatYS1CCBootloader-201231.hex
$ rfcat_bootloader /dev/RFCAT_BL_YS1 verify bins/RfCatYS1CCBootloader-201231.hex && rfcat_bootloader /dev/RFCAT_BL_YS1 run

i hope this helps :)

Thank you so much for the quick answer. As I understood from your message, I can get away without having to install SDCC v3.5.0 instead I just run the commands you mentioned after bootloader force is initiated - have I understood correctly? After I complete these steps will print(d.reprRadioConfig()) show the compiler version? Thanks

[atlas0fd00m]

correct.

Thanks again for your help, have run the above commands however "rfcat_bootloader /dev/RFCAT_BL_YS1 verify bins/RfCatYS1CCBootloader-201231.hex && rfcat_bootloader /dev/RFCAT_BL_YS1 run" is thowing out the following error:

I skipped the verify portion and did "rfcat_bootloader /dev/RFCAT_BL_YS1 run". I can now see the new firmware:

The issues I still have rx and tx still don't work:
Rx:

Tx:

Any suggestions on how to have this fixed? Also is there a way to uninstall rfcat from the raspberry and start with a new install?

Thanks for your help and patience

glad it helped.

i apologize, i apparently failed to copy/paste well, and added in the "bin/" part to the filename. thankfully, just for the verify part.

as for transmit:
this is now Python3:

d.RFxmit(b'HALLO') 

d.RFrecv() does throw a TimeoutException if a packet doesn't arrive within the timeout time.
are you sure this is an error? or just an actual timeout?

i should really do something about that ChipconUsbTimeoutException.... there's currently not a pretty way to make it something else, but that's the normal error if timeout occurs while waiting for a packet.

Thanks for all your support and guidance with this, much appreciated!

I keep forgetting that a lot of code is now using the python3, adapting the command works as expected. For the Rx I will need to do some further testing with an SDR or try to use the rfcat -s to be sure I was tunned to the correct frequency and check the Rx.

Again thanks for the help!
