To do so, log in to your Linux box via ssh and open the serial connection via minicom(1): sudo minicom -b 115200 -D /dev/ttyUSB0 Just connect the serial console via USB to another Linux box, and you have remote serial access to your ARM device. Many ARM devices offer serial access via USB, which makes it easy to manage console access. The most convenient way to interact with u-boot is via serial console. Compared to grub, u-boot doesn’t offer a high level of selfconfiguration or end-user friendliness, but it does offer a much smaller footprint.

U-boot is maintained by denx and published under the GNU General Public License version 2 (GPL-2.0+). U-boot is a boot loader similar to lilo or grub, but is specifically designed for embedded devices. The people from the ODROID Magazine kindly published this artice in their 2015-11 issue. If you need more flexibility, it is worth a deeper look into the u-boot internal structure Many vendors focus on an end-user friendly u-boot configuration. This is not something which helps me now (I am not going to desolder and replace these tiny SMD resistors on my IO shield), but it may be interesting for future boards.The majority of recent ARM based devices use "Das U-Boot" (u-boot) to load and start the Linux kernel. A baudrate of 230 kBaud then still is feasible, but going over 400 kBaud then becomes troublesome. I expect the level converter to have at least a parasitic capacitance in the order of magnitude of 10 pF and then the cutoff frequency easily drops to values as low as 1 MHz (f=1/(2*pi*R*C)). With the 10 kOhm resistors, I expect the cutoff frequency to be much lower than 10 MHz. At 10 MHz cutoff, you should be capable of 2 MBaud serial communication, reliable 4 MBaud may be doubtful/borderline. The level converter chip itself allows for bandwidth up to 10 MHz with a 1.8 V level on one side. 2.2 kOhm can increase the available bandwidth considerably, while still having acceptably low current (only max. To my opinion this is fairly high and I can imagine that the use of e.g. The used level converter requires the use of pull-up resistors and for this purpose, 10 kOhm resistors are used (R11 and R12 in the schematic of the Odroid U3 IO shield). These are connected to the ATMega328 through a level converter, which converts the RX and TX signals of the 8-pin jumper to 5 V level and v.v. I have studied the schematic of the I/O shield and I see that the 8-pin jumper has 1.8 V UART pins. Is this a limitation of the I/O shield, or of the UART, used for /dev/ttyACM99?

I, however, cannot go higher than 230400 bit/s. In the following thread I read that even 2 Mbit/s is possible: If, however, I choose higher values in the argument of Serial.begin(), like 460800, or values, which are more natural to the ATMega328P, such as 500000 or 1000000, then I get gibberish in minicom (of course in minicom I set the serial comm parameters, such that they match the value, supplied in the Arduino-sketch). The sketch, as shown, works with minicom if I set the serial comm parameters to 230400 8N1. wait 2 milliseconds for the AD converter to settle Int sensorValue = 0 // value read from the pot
