ERROR: Timeout waiting for ACK/NACK after 'Send data (0x24)'

I'm running
python3 cc2538-bsl.py -p /dev/ttyUSB0 -e -v -w --bootloader-sonoff-usb CC1352P2_CC2652P_launchpad_coordinator_20220219.hex -V
And I'm getting this output:
sonoff

I have tried different baud rates and I always get the same error. How can I fix this?
UPDATE:
I changed USB ports and now it works but I'm getting a different error:

ERROR: No response from target on status request. (Did you disable the bootloader?)
seems like in both cases your chip isnt answering after the write cycle. Are you sure you're using a correct firmware for your chip, and you're not disabling the bootloader in the chip?
@SuperPauly I was having the same issue. Decided to stop a bunch of user services. Homebridge, running on the same pi, seemed to be the culprit. Perhaps it was trying to access the same serial port for some reason? no idea
