I want to know the physical address range of the TX2 development board (please refer to here): First, I need to print the bootloader log information of the development board, and then obtain the physical address range based on the log information.
- In the TX2 development board, I used J21 (PIN8, PIN9, PIN10);
- The usb to ttl wire is FT232RL, RXD (white wire) is connected to pin 8, GND (black wire) is connected to pin 9, TXD (green wire) is connected to pin 19, and the red wire is not connected;
- The configuration information of minicom is as follows:
serial device: /dev/ttyUSB0
Bps/Par/Bits: 115200 8N1
Hardware Flow Control: No
Software Flow Control: Yes
However, minicom did not print any information, as if J21 did not transmit the information to the ubuntu PC.
may I know what is the reason?
Does TX2 enable J21 by default?
Before connecting J21 UART, do I need to do other operations to print bootloader information in minicom?
