Can't flash CC1352

[defuzzlog]

Hi.
Catsniffer isn't recognized in the Smart RF Sniffer 1.9 (already read and applied advice from FAQ wiki GitHub page - still no result). When I try to flash the firmware of the 1352 - nothing happens. I can upload "Serial Passthrough with bootloader", but
Flash Programmer 2 doesn't see the device and when I try to flash with python I get the error " Timeout waiting for ACK/NACK after 'Synch (0x55 0x55)". Also when I try to enter the bootloader through hardware first press the “boot” button and while holding it, press and release "reset", and finally release the “boot” button - nothing happens, it didn't work and No LED activity. Tried to run on three different computers, used different USB cables - nothing helps.

Is there any other way I can help to solve this problem? Maybe some additional data or logs are needed? And should I hope for a solution to this problem? Thanks

@defuzzlog CatSniffer is not compatible with version 1.9 of Smart RF Sniffer, you must use version 1.8 as indicated in our wiki.

when cat sniffer is in boot mode, there is no LED activity.

To ensure that the device is in boot mode press the BOOT button without connecting to the computer, keep the BOOT button pressed and then connect the device via USB, now release the BOOT button

Just checked in Smart RF Packet Sniffer 1.8 - it is doesn't detect Catsniffer.

Folowed you steps - press Boot and hold it until device connected via USB, release it after connection via usb. Doesn't help. It still can't find cc1352 over python cmd or flash programmer

Hello @defuzzlog Could you share pictures of your COM port on the device manager? in order to see if your system is detecting your board.

Hello, @defuzzlog Could you describe or share a video of the Led 4 behavior when you plug the USB, Please? Also, could you upload to the cat sniffer the serial passthrough and describe the behavior too?

Hello @defuzzlog thanks for the video, could you upload the SerialPassthrough.ino please and describe the behavior of LED D4, please?

Hello @defuzzlog thanks for the video, could you upload the SerialPassthrough.ino please and describe the behavior of LED D4, please?

Hi. No matter what ino file I upload (SerialPassthrough.ino or Serialpassthroughwithboot.ino) the behavior is the same - led d4 is off.
