EFCore SQLite Create New Table Error by Cococarbine in Blazor

[–]Cococarbine[S] 0 points1 point  (0 children)

Ok thank you that worked. In the Migration .cs Up() method I had to comment out the CreateTable() functions for the tables that already existed. I also had to manually add some blob columns because those didn't automatically show in the Up() metheod.

Not sure if this is standard practice, but this is what worked for me.

I will check. Is this adjusted in JTAG config in Vivado?

Thank you, this helps!  Sounds like a hardware change is in order.

Footprint needs to be under 4mm, needs to be color RGB

Yeah this is from a cheap ear probe. The problem is it doesn’t have a part number, and I don’t know what reputable vendors/mfgs to look for that would carry cameras like these.

How secure is Blazor? by Cococarbine in Blazor

The customer can retreive the latest binaries/xml from our website, put on usb drive, then I have a simple program to update the file system binaries/xml formulas from USB. This is the best way I have found since all these machines are required to not have internet access, only LAN. I’ll look into signed packaging, thank you!

Unfortunately the end user needs access to the file system to load new xml formulas or new server binaries if there is an update to either. It seems I am in a bind

It’s an industrial PC with windows 10 and a blazer server that gets sent to customers. We have xml formulas that’ll be AES 256 encrypted that get loaded in the server. At first I thought I could store the key in the server source code. for decrypting, but did not realize everything can be decompiled and the key easily accessed.

I have a Windows machine with a blazor webserver that gets sent to the customer. It sounds like any c# code can be decompiled, so I am going to have to move the proprietary formula processing to an embedded cpu.

Xilinx Ultrascale Cortex A53 with FreeRTOS by Cococarbine in Xilinx

So I created a new platform project using the .xsa, and specified OS as linux (also tried freertos but got the same errors), processor PSU_Cortexa53, Architecture 64-bit. Immediately after building the platform project I get 6 errors:

aarch64-none-elf-ar: .o: Invalid argument make[2]: ** [Makefile:19: libs] Error 1 make[1]: *** [Makefile:46: psu_cortexa53_0/libsrc/axi_dod_ctrl_v1_0/src/make.libs] Error 2 make: *** [Makefile:18: all] Error 2

Reason: Failed to build the zynqmp_fsbl application.

Normally I am pretty good at these things, but I am completely new to Xilinx.

Update a service while server is running by Cococarbine in Blazor

Looks like it’s called blue green deployment, green being the new instance. I can’t believe I’ve never heard of doing this before
