CC2652 unbricking with Raspberry Pi and OpenOCD

I was a bit quick when flashing my generic CC2652R and ended up dowloading and flashing firmware for CC2652P.. Since it was the wrong firmware, the bootloader also didn't work anymore, making me unable to flash the correct firmware with the integrated USB serial programmer.

Luckily the module has a cJTAG debugging interface, that should make it possible to flash directly onto the chip without the bootloader. But I don't have any serial debuggers, so I have had to come up withj my own from various limited information I could find.

Approach

Using OpenOCD we can use a Raspberry Pi as a JTAG debugger. It does not support cJTAG for debugging, so it will instead send a signal to make the CC2652 switch to normal JTAG. We will then have to connect a few additional cables to the TDO and TDI pins for a full 4-pin JTAG connection.

mitmproxy addon for handling oauth access and refresh tokens automatically
# run: mitmproxy -k -p 8090 -s mitmproxy-jwt-refresh-addon.py
# set burp upstream proxy to localhost:8090
#
# use case:
# - application authorization is implemented by OAuth 2.0
# - testing is performed using Burp as primary and mitmproxy as upstream proxy
# - mitmproxy takes care of the Authorization tokens using this addon
# - user gets an access_token and a refresh_token during the 1st login (e.g. password login)
# - mitmproxy addon caches access_token and refresh_token
# - mitmproxy addon adds Authorization: Bearer [access_token from cache] header for every request

Collection of CAN bus packages and tools

Collection of CAN bus packages and tools

This document assumes the use of Linux as the chosen development platform. Items in bold are highly recommended.

It is recommended to use SocketCAN when working with CAN bus on Linux. It is supported by the Linux kernel mainline and follows the Linux interface model, allowing you to use other network tools such as Wireshark. This also allows the creation of virtual CAN interfaces where no physical hardware is required to simulate or replay CAN messages.

[Reload PostgreSQL config] After updating pg_hba.conf or postgresql.conf, the server needs the config needs to be reloaded. #postgres

After updating pg_hba.conf or postgresql.conf, the server needs the config needs to be reloaded. The easiest way to do this is by restarting the postgres service:

service postgresql restart

When the service command is not available (no upstart on Synology NAS, for example), there are some more creative ways to reload the config. Note this first one needs to be done under the user that runs postgres (usually the user=postgres).

user#  sudo su postgres
postgres#  pg_ctl reload
