Not working as expected

[KB8RCO]

I haven't messed with sondes since last fall. One of our club members has started "collecting" them again, and I seem to be the depository.
Last fall, I thought I had good output from the sondes, but I downloaded the latest firmware and things seem to be different:
Maybe I am doing something different?

The output doesn't seem to read any of the sonde sensors (except internal temp). GPS seems okay.
Here are the issues I am seeing:

1. On a couple of RS41 sondes, I see an "ERROR: last block must be <= 15" when I run
   openocd -f ./openocd_rs41.cfg -c "init; halt; flash protect 0 0 63 off; exit"
2. And then I program it and see:
   Info : stm32f1x.cpu: hardware has 6 breakpoints, 4 watchpoints
   Info : starting gdb server for stm32f1x.cpu on 3333
   Info : Listening on port 3333 for gdb connections
   target halted due to debug-request, current mode: Thread
   xPSR: 0x01000000 pc: 0x08001c00 msp: 0x20001910

I don't know how to set breakpoints or watchpoints, so not sure how this happened or how to get rid of it.

Also, None of the sonde seem to report sensor data. It is always "Zero".
Well, $ti and $bv seems to work, but $te, $hu,and $pr always report zero?
Are they only for Si5351 bus devices? I thought the firmware read the existing RS41 sensors?

Any help?
