CheckSum Error on MacOS Sonoma 14.4

[zsoohoo]

I am trying to update a device using a Macbook pro with Sonoma 14.4 and am receiving an error message that states that nordic "Did not receive checksum response from DFU target." I am able to update the same device on my windows machine. This is through the DfuTransportSerial module from v6.1.7 of the nordicsemi library. I'm not sure if this is an issue specifically with macs. Any help would be appreciated!

Hello,

It may be an issue I can report, but before I do that, can you try the following (from Windows or Mac):
Run JLinkExe, then run MSDDisable in the J-Link Commander interface.

I have seen reports this can fix issues in general, make sure to disconnect and reconnect the board afterwards (to ensure it re-enumate).

You are using which version of nrfutil and segger j-link?

The error "Did not receive checksum response from DFU target" on macOS Sonoma could be due to compatibility issues with the Nordicsemi library v6.1.7. You can try checking the serial port permissions, ensuring the correct baud rate, using the nRF Connect for Desktop tool, or updating the Nordic library. These steps might resolve the issue you're facing on macOS.
