Does anyone have any experience with the Augentix HC1703 chip?

[Jalecom]

Hi dhigginb, glad to know it works for you too!

If you have a chance to browse the files of your camera check the start.sh and tell me if you have "devmem" commands: on my cameras I found it 8 times at the lines 54, 55,56, 57, 573, 574, 581 and 582 (see AJ_HC1703L_Teardown/tmp/start.sh at main · Jalecom/AJ_HC1703L_Teardown) and I have no idea of the purpose. I can figure out a low level write to enable a device; maybe the whatchdog ?!? Maybe a GPIO configuration ?!?
Additionally if your start.sh is similar to mine, you can put in the debug_cmd.sh only the commands you need and exclude the unwanted ones. If you don't need to access the camera from outside your network, you can stop/block/prevent the comunication with the chinese server with the hosts file (see zsgx1hacks/readonlysd/hack/hosts.new at master · ant-thomas/zsgx1hacks). You can even kill the start.sh itself.

Hi Jalecom, long time no see, I apologise for the really long delay, i've had school and just completely forgot about this until a couple days ago, decided to try and hack the camera again, So I tried the script from the github repo, however i'm having an issue where nothing is happening at all from what I can see, no web ui, no ssh, no ftp, if I had to guess my camera does something different from the rest, and so I am trying to use UART, and I got a device which can read it, however my wires are quite thick which would mean it would take a while for me to even get them on the correct pin, and I was wondering, if you could potentially see any pins which could be the TX pin? (I posted an image of the wire for reference) I know in an earlier post you told me a potential one, but it's been a couple months and you might've learnt something since then. I do apologise for this, but it's just because I haven't had much experiences with circuit boards.

Here's the update file by the way in case this helps in any way

Hi GYKGAMER, I am also trying to get more information about this camera, in particular I'd like to understand the structure of the upgrade file.
Thanks for sharing the file!
Can you point to the source of that file or where I can find other versions of the firmware upgrade?

About the UART connection, I managed to access the bootloader logs by connecting the UART adapter directly to the SoC pins marked by Jalecom in this post, using self made wires with sewing needles at the tip.
The bootloader on my camera disables the linux kernel logs by default, so you'll need to edit the bootargs in the env to enable it.

My source is that I used the app to update the camera, and then the file got saved to the micro sd card. I don't know what server they used, or the link to it. So I do apologise. However are you sure that those pins are correct? Are you able to send a photo of your setup and what you did?

 

[Hafiz0]

I see, thanks for the info.
The pins are correct as I can send and receive logs as I said.
I don't have my setup with me, but basically I inserted a sewing needle in the female connector of a dupont wire and keept its head as steady as I could on the SoC pin that Jalecom marked as TX.
Keeping the needle on that super tiny pin has been a real pain in the a$$, but it worked.
I connected the other side of the dupont wire to an UART to USB adapter connected to my pc and open a TTY to see the logs as usual.

Alright, thanks for explaining that, may I ask, you mentioned "you'll need to edit the bootargs in the env to enable it", are you able to explain what you did there to get the bootargs? I mean, if I can't access uart boot logs, how am I supposed to enable UART at all?

My SOC try to run a debug scripts in the boot process and if you create a file debug_cmd.sh on an SD card and you will be maybe able to execute bash commands from it. Note my SD card is mounted in /mnt and my camera looks for /mnt/debug_cmd.sh similary to the Goke GK7102.

Yes I understand, but mine doesn't work that way, my camera either doesn't see debug_cmd.sh, or just ignores it, which is why i'm trying to find the UART pins, I want to see how you guys have it set up, and what you guys did step by step to get a result.
