I’ve recently gotten the debian image via the torrent.
After flashing to a microSD card, I’m able to hook up my USB-Serial connector (this model from adafruit, it seems to need the power pin also connected to work…not just the three wires specified in the guide) and get through the boot process into the system and login through the serial terminal. At this point, it is connected to the network, ssh is working, etc.
Now I’d like to normalize the boot process a bit, so that it will startup without having to have the serial cable connected.
Reading the last two pages of the Quick Start Guide, it indicates that there are four options I can set the “Boot Mode” jumpers to:
Boot Mode | RGPIO_0 | RGPIO_1 |
---|---|---|
1-bit QSPI Nor Flash | 0 | 0 |
SDIO3.0 | 1 | 0 |
eMMC | 0 | 1 |
UART | 1 | 1 |
I’m guessing SDIO3.0 might be for SD cards??? But I’m not familar with that acronym.
Then there is the question of what setting actually means 1/0.
I think the guide indicates that having the knobby part to the left is high/1 and right is low/0. Is that correct?
Also, it is a bit confusing but the RGPIO_1 is on top and RGPIO_0 is bottom.
Thus on my board
[ -> ] RGPIO_1
[ <- ] RGPIO_0
should get me SDIO3.0?
