[compilation] Correct path to stlink/chips subdirectory

[letshin]

Hi - I am not sure if these are two separate issues but after compiling from this repo I get the following error with a E73-2G4M08S1EX (nRF52833) connected.
Commandline input:

st-info --probe

Commandline output:

/usr/share//stlink/chips: No such file or directory
Found 1 stlink programmers
  version:    V2J29S7
  serial:     50001000030000544334544E
  flash:      0 (pagesize: 0)
  sram:       0
  chipid:     0x000

Is it normal for "/usr/share//stlink/chips: No such file or directory" to appear?

Not sure if its related but while running PYOCD I get the following

Commandline input:

pyocd load s140_nrf52_7.2.0_softdevice.hex --target nrf52833

Commandline output:

I am facing the same problem on MacOS (see the error message below):

% st-flash --reset write build/main.bin 0x8000000
st-flash 1.7.0-217-gf93adb9
/usr/share//stlink/chips: No such file or directory
Failed to enter SWD mode
Failed to connect to target
make: *** [flash] Error 255

How do I fix this problem?

[weiminshen99]

Good news. I fixed the problem by changing one line in CMakeLists.txt, because new Mac does not like people to change /usr/share, but /usr/local/share is OK:

-# Define install directory /usr/share
-set(CMAKE_INSTALL_SHAREDIR /usr/share/)
+# Define install directory /usr/local/share [not /usr/share on MacOS]
+set(CMAKE_INSTALL_SHAREDIR /usr/local/share/)

The whole thing is now installed and working on my MacOS. I also write a paragraph in README for "Installation on Mac". Please let me know if you want that too.

I was using it on linux, but didn't bother debugging. I instead returned it to Amazon and purchased a DAP_LINK adapter from eBay and used pyocd with it. This means I can't text your fix :(
