Error message unclear with alpha.47

Toit

#Error message unclear with alpha.47

Thread channel in help

I just updated toit from alpha.35 to alpha.47, and now every error message is the same.

I got this error message with a modified primitive function, because I entered a wrong argument. Now I'm getting this and I know the problem is related to the UART. I'm decoding with the snapshot used to generate the bin file. Don't know if this is a bug, or my update went wrong. I've reinstalled toit with same outcome.

(error message in next message because of discord thread character limit)

Decoding by `jag`, device has version <2.0.0-alpha.47>

How do you decode the error messages?

Rikke 01/05/2023 01:28 PM

I'm using erics script

ar p ../output/test.snapshot uuid | hexdump -e '4/1 "%02x" "-" 2/1 "%02x" "-" 2/1 "%02x" "-" 2/1 "%02x" "-" 6/1 "%02x" ".snapshot"'

floitsch 01/05/2023 01:29 PM

ok. that gives you the correct snapshot (hopefully).

floitsch 01/05/2023 01:29 PM

But then you call a tool to get the stacktrace.

floitsch 01/05/2023 01:29 PM

Looks like it's tools/system_message.toit.

floitsch 01/05/2023 01:29 PM

Is that tool up to date?

floitsch 01/05/2023 01:30 PM

The system_message tool must be aligned with the snapshot.

floitsch 01/05/2023 01:30 PM

It's not (always) possible to use a system_message tool from one version with the snapshot of another.

Rikke 01/05/2023 01:30 PM

I updated all my packages and reinstalled toit by cloning a new one on git. How do I update the system_message tool

floitsch 01/05/2023 01:30 PM

It comes with the toit checkout.

floitsch 01/05/2023 01:31 PM

Is the snapshot that makes problems compiled with the latest toit, or still from an older Toit version?

Rikke 01/05/2023 01:32 PM

Its compiled with alpha 47

Rikke 01/05/2023 01:33 PM

I'm using the /toit/build/host/sdk/bin/toit.compile to make the snapshot

floitsch 01/05/2023 01:33 PM

can you send me the snapshot?

floitsch 01/05/2023 01:33 PM

[email protected]

Rikke 01/05/2023 01:34 PM

Sure, give me a second

floitsch 01/05/2023 01:34 PM

(and maybe the base-64 message).

That's what I get.

floitsch 01/05/2023 01:38 PM

Is that realistic?

Rikke 01/05/2023 01:39 PM

Yes, I guess my jag is broken. I will try and reinstall. Thank you

floitsch 01/05/2023 01:39 PM

can you do a jag version ?

Rikke 01/05/2023 01:39 PM

Version:     v1.7.12
SDK version:     v2.0.0-alpha.44
Build date:     2022-12-02T14:21:56Z

floitsch 01/05/2023 01:40 PM

Try to update your Jaguar.

floitsch 01/05/2023 01:40 PM

I just tried it with jag v1.7.14 and there it worked.

Rikke 01/05/2023 01:40 PM

Okay, thanks

floitsch 01/05/2023 01:40 PM

Similarly, if you use system_message.toit you need to update it.

Rikke 01/05/2023 01:41 PM

I've never used system_message.toit

floitsch 01/05/2023 01:41 PM

ok.

floitsch 01/05/2023 01:41 PM

it's the tool that jag decode uses.

floitsch 01/05/2023 01:41 PM

If you update jag it should automatically use a newer version.

Rikke 01/05/2023 02:36 PM

Now that my jag works, I found a little mistake in the wifi.toit

******************************************************************************
Decoding by `jag`, device has version <2.0.0-alpha.47>
******************************************************************************
As check failed: an int (100) is not a string.
  0: string.+                  <sdk>/core/string.toit:399:14

******************************************************************************

Thesignal_strength call has changed since alpha 35, and now it actually asks for the SSID and not RSSI.

signal_strength -> float:
    info := (client_ as WifiServiceClient).ap_info handle_
    rssi := info[WIFI_SCAN_SSID_]
    // RSSI is usually in the range [-100..-35].
    rssi = min 65 (max 0 rssi + 100)
    return rssi / 65.0

Changing the rssi := info[WIFI_SCAN_SSID_] to rssi := info[WIFI_SCAN_RSSI_] works

the wifi.toit is found under /lib/net/wifi.toit

floitsch 01/05/2023 02:38 PM

Thanks!
