Description
When I try to set a breakpoint, for example on mbedtls_ssl_handshake in the test example below:
https://github.com/marcuschangarm/mbed-os-example-tls/tree/master/tls-client
I get this error:
(gdb) break mbedtls_ssl_handshake
Cannot access memory at address 0x3001c660
pyocd-gdbserver: 0.8.1a1 and 0.8.1a2.dev38
DAPLINK: 0241
GCC: 5.4.1 20160609
GDB: 7.10.1.20160616-cvs

Research direction
Reproduce the failure with the linked mbed-os-example-tls/tls-client example and the mbedtls_ssl_handshake breakpoint on the Realtek RTL8195AM. Start at the pyocd-gdbserver breakpoint handling entry point and compare the reported versions and DAPLINK details. Done means identifying and fixing the cause, with the breakpoint setting successfully on this target.
