I have a question for you.
The FPGA I use is your tinyfpga Bx.
Can I replace the FPGA bootloader with a user-defined binary file?
If no.1 is available, I would appreciate it if you could tell me how to do it in detail.
If no. 1 is not possible, ultimately what I want is that when I apply the power (with usb cable) to the fpaga, I want all pins (except the vin pin) to output LOW (0V).
Is there any way to do this?
