Chip Shouter fault_temp_sensor

Schweik · June 14, 2022, 5:21am

Hello,

I’ve raised that question before, and I got a new firmware build, but my CS keeps getting fault_temp_sensor errors. Is there currently a way around that?

Hi,

What firmware version are you on? I think I’ve fixed the error, but it’s a little hard to say because the underlying cause isn’t consistent.

Version is GKHZ2N:2.0.2

Sorry about the late reply here, ended up getting sidetracked with the new release. 2.0.3 is the newest firmware and that should fix the temp sense issue

# ChipSHOUTER Firmware Update

## Downloading Firmware Update File

The firmware update file is downloaded from the following URL: https://media.newae.com/cw520fw/all_devices/cw520_XXXXXX_2-0-3_firmware.fup

You need to replace XXXXXX with the board id.

## Firmware Update Releases

### 2.0.3
Fix temperature sensor lockup when read during glitching. Should make trigger_safe unnecessary

### 2.0.2
Fix occasional lockup which causes device reset

### 2.0.1
Change trigger_safe behaviour

Hi!

Just wanted to add here, I updated my ChipSHOUTER to this firmware version and it seems to have removed the need for checking trigger_safe between arming and actually triggering (see my other thread).

One thing though: the .md file does not mention how to actually update. I was running with the chipshouter package from pip and it seems that does not contain the firmware update functionality.

So if you try to update the firmware, make sure to clone from github and do pip install . from the repo. Then do something like this from a python console:

>>> from chipshouter import ChipSHOUTER
>>> shouter = ChipSHOUTER("/dev/ttyUSB1")
>>> shouter.update_firmware("cw520_xxx_2-0-3_firmware.fup")
Connection successful
Sending: cw520_xxx_2-0-3_firmware.fup
Checking board ID...
Board ID matches file.
Attempting reset - you may need to power cycle ChipSHOUTER NOW with some versions.
You will hear ChipSHOUTER reset, but sometimes you need power cycle to allow update.
Sending reset for download .... [0]

After this I still have the “issue” that trigger_safe returns False for a while after arming the CS, but it does not generate errors when triggering anymore.

Thanks, I’ll try it out and report on the results.
