I was rechecking now the problem of consecutive small reads:
Sending packet: $m152bfc0,4#c0...Packet received: 2f757372
Sending packet: $m152bfc4,4#c4...Packet received: 2f6c6962
Sending packet: $m152bfc8,4#c8...Packet received: 36342f72
Sending packet: $m152bfcc,4#f3...Packet received: 65646c61

and they come from target_read_string - which you already solve in the other
thread.  I had wrong expectation they come from large memory transfer
requests.


Thanks,
