Hard Ware Tests from U-Boot

1. New Command will be added to the U-Boot:

• u-boot>chkboard

> command will get one parameter which check to run one specific check or all checks:

>chkboard RS-232 100

usage: chkboard RS-232-2 LoopCount

Loop Back Cable/Connector will be used to connect: RS232-2 Tx to RS232-2 Rx

UART2 Should be configured as RS-232 using the RS232/RS485 selection GPIO
