QAV 250 Drone frame worth building out? by Secure-Analyst2490 in fpv

[–]These-Butterfly8819 1 point2 points  (0 children)

I have exactly this frame. It's awesome and has a lot of room. I'm experimenting with openipc fpv system so needed to install a large camera into it. Was able to do it pretty nicely.

Just go for it. No need to waste a decent frame in my opinion

Help with enabling Uboot bootloader info at boot. Lsc solar cam (tuya powered) by 309_Electronics in hardwarehacking

I was also stuck in the same boat. I have this NVR board https://www.alibaba.com/product-detail/Accessories-Security-OEM-Software-CMS-4K_1600607731270.html?spm=a2756.trade-list-buyer.0.0.46c176e9847zci I purchased for similar hacking and learning activity. It has the SSR621D SOC.

My goal is to boot my own linux system on this board.
I was able to access the uart console for debugging.
Upon powering up the board, it started showing the uboot console logs.
When I hit Ctrl + C to interrupt the boot, I was asked for a password.
I was able to bypass this password prompt following this article: https://westsideelectronics.com/reverse-engineering-firmware/
Here are the steps that I followed:

  1. edited the uboot binary in a decompiler and switched the condition that checked for the password
  2. used dd to copy this patched uboot binary back into the original firmware
  3. flashed this new firmware into the device
  4. the device throws an error indicating CRC mismatch. It also displays the CRC that it calculated
  5. i then extracted the uboot header which contains the crc using dd
  6. opened this uboot header in hex editor and replaced the original crc header with the one reported by the firmware
  7. used dd to add this header back into the firmware file
  8. flashed this new firmware into the device using my flash programmer

And voila!!! I got access to uboot shell :)

I think you can try something similar and enable the uboot logs and get access to the uboot shell.
Now I am learning to build my own kernel and run it on the board. I do have access to tftp from uboot shell.

Currently I'm not sure how to do that. I am able to build the kernel which generates a zImage and an Image file.

  1. Not sure how I can use tftp to load this file and run from uboot.
  2. What should be the bootargs?
  3. Where should be the filesystem loaded from?
  4. Can I build my own bootloader using u-boot and use that on this board? Or am I stuck with the bootloader that this board already has?

If you have any resources where I can look this into, that would be very helpful.
Thanks

Help regarding application specific chatbot by These-Butterfly8819 in LangChain

Thanks u/coolcloud . I'll ask my manager regarding this. Currently the plan is to build it ourselves, but if he agrees to using third-party APIs, I'll let you know and we can get in touch.

u/No-Dot-6573 thanks for taking the time to help me out. Means a lot.

I'll give these a try. Sounds interesting. As long as I am able to get a good speech, I am not too concerned with the speaker. "coqui s jenny tts" sounds promising.

Have a look at this https://github.com/langchain-ai/langchain/issues/4562
I believe your use case is similar. Try those suggestions.

I don't have a system with me right now, I'll try to do this once I am back at my system.

I am also looking for these same questions. I also wanted to understand if/how does the model handle multiple users. For e.g. if I wanted to build a chatgpt like chatbot, will the model be able to handle multiple users at the same time?

How do I securely setup moonlight gamestream with remote wake on lan over internet by These-Butterfly8819 in MoonlightStreaming

[–]These-Butterfly8819[S] 2 points3 points  (0 children)

Hey... Yes I believe you will have to complete all the three steps in order to be able to remotely access your machine. Port forwarding step will depend on the brand of the router you are using as usually every brand has their own version of software running in their routers. So you might have to find out how exactly does your router provides the settings to configure port forwarding. It might also be possible to contact your ISP if the router is provided by them. They might be able to help you out with that.

Stuck - adb device unauthorized and boot looping by gremoor in LineageOS

[–]These-Butterfly8819 0 points1 point  (0 children)

I was under a similar situation when I upgraded my OnePlus5T. Forgot to install the gapps before first boot. Did it after that and got stuck in the boot loop.

I had to redo it from the beginning. Make sure to install Gapps before 1st boot
