Hello,
i have a strange issue here:
when i use hw version, i recieve:
proxmark3> hw tune
#db# Measuring antenna characteristics, please wait...
#db# Measuring complete, sending report back to host
# LF antenna: 14,50 V @ 125.00 kHz
# LF antenna: 21,08 V @ 134.00 kHz
# LF optimal: 26,45 V @ 130,43 kHz
# HF antenna: 1,00 V @ 13.56 MHz
# Your HF antenna is unusable.
proxmark3> hw version

uC: AT91SAM7S256 Rev B
Embedded Processor: ARM7TDMI
Nonvolatile Program Memory Size: 256K bytes
Second Nonvolatile Program Memory Size: None
Internal SRAM Size: 64K bytes
Architecture Identifier: AT91SAM7Sxx Series
Nonvolatile Program Memory Type: Embedded Flash Memory
when i type hw tune again i recieve:
proxmark3> hw tune
Sending bytes to proxmark failed
proxmark3>
i am able to reproduce this over and over again.
typing hw version makes my proxmark unusable until reset
the device is connected then /dev/ttyACM1
and then /dev/ttyACM2
and so on
?! any ideas how to solve this issue? Device was bought directly from proxmark3.com
thanks for reading and answering this post

The hw version command does 'kill' the device, in one known version just after we switched to git. See https://github.com/Proxmark/proxmark3/issues/10 for more info
