Re: Flashing custom bitstream

Hi,

thank you Kristoffer and Jonas. It is working now (at least the flashing; my bitstream apparently not so :?)

Re: Flashing custom bitstream

Hi Kristoffer, thanks for your effort and respone, but unfortunally it still wont work. It fails, when I try to flash the bitstream with the following message: Reset to bootloader mode ... Could not save cache, no writable directory Could not save cache, no writable directory Exception while doing c...

Re: Flashing custom bitstream

Hi, thanks for your response. I've tested your suggestions, but I'm still quite certain that it doesn't work. Here are the reason therefore (the test bitstream is unrelated to the LH project): 1. Using the cfloader generates the following output: Reset to bootloader mode ... Could not save cache, no...

Re: Flashing custom bitstream

Hi, thanks for you response. But I don't think this worked, since 1. the status of the bootloader stays IDEL and the connection is immedeatly lost when I press program. 2. the LEDs on the LH stay and work as they were with the release file, even though my test bitstream has no logic controlling them...

[SOLVED] Flashing custom bitstream

Hi, currently I'm struggling to flash the ICE40 of the Lighthouse system with a custom bitstream. First tried to to use the <paht-to-lighthouse-bootloader>/scripts/uart_bootloader.py /dev/ttyUSB0 lighthouse.bin command. Is my assumption correct that the /dev/ttyUSB0 shall be the Crazyradio PA dongle...

Using 2 Lighthouse decks with different configurations

Hi, I'm planing to use two Lighthouse decks with one Crazyflie (one for positioning and the other one for specific calculations on the FPGA). My question is, how can I flash those two with differnt bitstreams, since both of them have the same internal name (bcLighthouse4) and so will be handled by t...
