Hi BBB community, We have a BBB Clone hardware with only serial UART as the only communication port to our board at the moment (USB port is not working due to hardware issues) So this is where I am at this moment, looking for advice to go forward. HW Description: Chip: AM3358BZC100 eMMC: Manu

Hi Gerald, I meant "strap values", not connections on the board. As far as I understand it, correct strappings alone cannot always ensure correct bits in the respective registers of the transceiver chip. The power-on and reset timing is also important, and this timing, unlike strappings, is dif

Oh, and in the case of Nodejs, you could use g_ether, and stream the data via socket.io, and have the client side Javascript do all the heavy lifting. It is a rather cool "thing" to do. I am just not sure this is the best way to go about things. On Fri, Nov 21, 2014 at 2:11 PM, William Hermans wr
