humility does not expect 0x prefix on hex numbers from openocd #560
Description
It looks like recent versions of openocd changed how hex strings are represented.
With this environment:
OS: Ubuntu 24.04.2 LTS
openocd version: Open On-Chip Debugger 0.12.0
This was found trying to run cargo xtask humility app/demo-stm32h7-nucleo/app-h753.toml -- tasks from the hubris repo.
openocd was started like this:
$ sudo openocd -f src/oxide/hubris/chips/stm32h7/openocd.cfg
Launching cargo xtask ... looks like this:
$ cargo xtask humility app/demo-stm32h7-nucleo/app-h753.toml -- tasks
humility: attached via OpenOCD
humility tasks failed: failed to read image ID at 0x8005530; board mismatch?
Caused by:
invalid digit found in string
Error: humility failed
The output on the openocd console looks like:
Open On-Chip Debugger 0.12.0
DEPRECATED! use 'read_memory' not 'mem2array'
0 0xc8 1 0x12 2 0xfc 3 0x90 4 0xe0 5 0xfc 6 0xfa 7 0x24
0x20000dc0
DEPRECATED! use 'read_memory' not 'mem2array'
0 0x72 1 0x5c 2 0x3c 3 0x0 4 0x0 5 0x0 6 0x0 7 0x0
0x20000dc0
Looking at the humility code, it looks like humility does expect to see 0x in the hex numbers.
