aslowik Posted January 11, 2021 at 08:29 PM Share Posted January 11, 2021 at 08:29 PM Hi, how to flash firmware into a 1.4 Raspberry HAT module that does not show on USB? The HAT was operational, and unfortunately I connected from remote over WLAN and started a firmware update. The connection broke after a few seconds and now the HAT remains in some special state. Status LED is flashing, but module does not show on USB if I connect to the USB-port on the HAT module, neither from Raspberry nor some from other MAC OSX computer. I power-cycled the Raspberry a couple of times already, but behavior remains the same. Quote Link to comment Share on other sites More sharing options...
photron Posted January 12, 2021 at 02:25 PM Share Posted January 12, 2021 at 02:25 PM The USB port on the HAT Brick is power only. The problem you're running into now is that the HAT Brick is in bootloader mode and in this mode the HAT autodetection of the Raspberry Pi doesn't work. Otherwise the HAT Brick you just show up in Brick Viewer and you could just flash it. You need to manually edit the /etc/brickd.conf file on the Raspberry Pi and add these lines to the end of the file: bricklet.group0.spidev = /dev/spidev0.0 bricklet.group0.cs0.driver = gpio bricklet.group0.cs0.name = gpio23 bricklet.group0.cs0.num = 23 bricklet.group0.cs1.driver = gpio bricklet.group0.cs1.name = gpio22 bricklet.group0.cs1.num = 22 bricklet.group0.cs2.driver = gpio bricklet.group0.cs2.name = gpio25 bricklet.group0.cs2.num = 25 bricklet.group0.cs3.driver = gpio bricklet.group0.cs3.name = gpio26 bricklet.group0.cs3.num = 26 bricklet.group0.cs4.driver = gpio bricklet.group0.cs4.name = gpio27 bricklet.group0.cs4.num = 27 bricklet.group0.cs5.driver = gpio bricklet.group0.cs5.name = gpio24 bricklet.group0.cs5.num = 24 bricklet.group0.cs6.driver = gpio bricklet.group0.cs6.name = gpio7 bricklet.group0.cs6.num = 7 bricklet.group0.cs7.driver = gpio bricklet.group0.cs7.name = gpio6 bricklet.group0.cs7.num = 6 bricklet.group0.cs8.driver = gpio bricklet.group0.cs8.name = gpio5 bricklet.group0.cs8.num = 5 as described here: https://www.tinkerforge.com/en/doc/Hardware/Bricks/HAT_Brick.html#compatibility-to-other-boards-and-images Afterwards reboot the Raspberry Pi, then the HAT Brick should show up in Brick Viewer again and you can flash it. One the HAT Brick is flashed success fully, edit /etc/brickd.conf again and remove the lines you just added. Quote Link to comment Share on other sites More sharing options...
