I wanted to ask about the bootloader behavior. The situation is like this:
- TinyFPGA Bx connected through USB
- Then , programmed through
- The program is correctly written, both power and boot LEDS switch off less than one second and my FPGA configuration start to work…
- But my configuration only works for one second or so! I can see the blinking example working as expected during that second.
- Then the bootloader comes again and my configuration stop being active, only bootloader.
- I can repeat many times using
tinyprog -bbut again it switches into my configuration only for one second and then come back to the bootloader.
This is the intended behavior when the USB cable is connected? I should just use the USB for programming and then use the power supply during development?
My computer is Lenovo Thinkpad X1 carbon with Ubuntu 18.04.
Also the installation of tinyprog (or apio, not sure) already modified the udev rules for preventing the ModemManager to send commands so I think that is not the problem.
Thank you for your help.
