A2300 B1.01 Firmware Dump

Hi, I dumped firmware from a2300 using Canon Basic/Scripts/Dumper.  File is available here: PRIMARY.BIN.gz

I tried to get firmware version using reqs.ver and acid tool without success.  Using exiftool I got the following:
Code: [Select]
$ exiftool a2300_xxx.jpg | grep Firmware
Canon Firmware Version          : Firmware Version 1.00
Firmware Revision               : Beta 1.01 rev 0.00

From stubs_entry.S file I got:
Code: [Select]
// Camera info:
//   DRYOS R50 (DRYOS version 2.3, release #0050)
//   Firmware Ver B1.01
//   Canon PowerShot A2300

It is the first time that I saw a beta firmware dump, I don't know how it should be identified in chdk, B1.01?

This is strange. Looking at the dump, I agree, it doesn't have the usual GM... version. For the sub directory and camera_list.csv, think b101 is as good as anything else for now.

I can't think of anything offhand in the CHDK source that requires the NNNa format, but if there is we'll find out soon enough.

Since this is an R50 camera, you'll want to check out the sx260 thread: http://chdk.setepontos.com/index.php?topic=7889.0

If this is actually a beta, it might have extra debugging strings, which could be quite useful. From what I understand, something like this in the very early days helped get CHDK started.

Do you know if this camera purchased through normal retail channels, or was it a review model or something like that ?
Don't forget what the H stands for.

Well, I 'm using a2300/sub/b101 directory for the code and the "make" command is working without problem.

I don't know the details, but I guess that camera was not purchased through normal retail channel.
