I have followed the qualcomm instruction on how to build and load a new image onto a dragonboard using fastboot.
My problem is that I keep getting an error after loading my new image onto the board:
GPT: (WARNING) Primary signature invalid
Can someone please help me on how to resolve this? I really cant find much online. I did find one post about zapping the GPT data and that method worked once to successfully boot a core-manage-minimal but now I want to load my custom build. I have used the core-image-sato as my base and added curl,sqlite3,nfc into the local.conf, put the meta-nfc in the main director and in the bblayer.conf as well as enabled nfc in the kernel.
I am unable to get a build to work following the QUALCOMM instructions on their sight. It says to use the BSP for your HLOS but What HLOS? the system I am developing on? the once in the BSP ? how do I do this? I keep getting the GPT: (warning) Primary Signature is invalid. I followed the instructions on signing the file, even corrected their flashall script as it was flashing the unsigned version.
PLEASE help, I have had to reload my system at least 10 time today because this error ‘bricks’ the DB410C There has to be a simple way to fix this.
Yes I am trying those bsp’s trying to find one that works. I have a rescue sdcard that I am using to reload the system when I need it. I wish the dragon board bsp would generate the sdcard image… it’s very frustrating, been working on this for 4 days now. Keep getting this error. Can’t find anyone on any forum with same issue.
No, all Linux. not sure if java is the right choice for this product. I have had it out in industry for 8 years and am now working on the new version. Was on the Rabbit Semiconductor RCM3100 processor. moving to embedded Linux on the DB410c as it had a really solid feature set like GPS as well as the standards. I need to build a custom kernel with NFC, CURL, SQLite3 so far. (who knows what comes up during design/build) Will also be using BLE but must likely offloaded to a cypress BLE with mesh.
So I have deleted all files in the project directory and am doing a fresh build thinking something may be corrupted. will see when done…
