This is maybe not the right category, but I did not find better.
I was building a surveillance system with 4G LTE and wan connection to the “headquarter”. In the warehouse there will be several cameras, a NVR and some checked doors, also some lights and locks will be remote controlled. So I needed a 4G LTE router with wan, some LAN and digital IO. I found BPI-R64 and bought one. I have several (open source) routers and I thought that BPI-R64 works in the same way, just plug in, define parameters, but no. I found some images that worked so and so. I established a development environment to be able to build new images, not very successful. So I decided to wait for a working image. Now I have been waiting about a year, but nothing is working as I expected. My latest download is mtk-bpi-r64-SD-OpenWRT-Router-20210501. I flashed it and booted. After a while I get a lot errors e.g.
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x1a620000: 0x736d instead
I have also learned, that EC25-G hardly will be working in PCIE slot.
My background is in mainframes and in Windows. I also have some experience in embedded system. I have no time to study Linux so much, that I can build my own router.
Some time in last autumn, I think, there was instructions in youtube and also a link to an image, that worked quite well (Luci), but it is not any more there and I managed to lose the image. On the other hand, it did not connect to the provider, Elisa or Telia.
Now I would like to know, will there be in the near future an image, that takes care of basic LTE router functions so that I need only define some parameters. I had to buy for the project a replacement, RUT955, that has about the some features and works fine. If needed I can also program it.
I must admit, that I understood open source wrong. I thought, that it means a system that works, but because I can get the code, I can make it better or more suitable, but that seems not to be the case.
In the marketing material there should be emphasized, that BPI-R64 is only a hardware and the buyer has to provide the program by him/her self.
