This is configured in RCW fields UART_BASE and UART_EXT.

The T1024 device supports several options for RCW source - NOR, NAND, SPI and SD card. For example, you can configure your board to boot from SD card. SD card deployment is described in Linux SDK documentation.</P></BODY></HTML> Wed, 10 May 2017 06:37:07 GMT https://community.nxp.com/t5/T-Series/Second-UART-on-T1024RDB/m-p/673816#M2044 alexander_yakov 2017-05-10T06:37:07Z Re: Second UART on T1024RDB https://community.nxp.com/t5/T-Series/Second-UART-on-T1024RDB/m-p/673817#M2045 <HTML><HEAD></HEAD><BODY><P>Thank you much, we were able to flash updated RCW into NOR and now second UART port works ok.</P></BODY></HTML> Wed, 09 Aug 2017 05:25:21 GMT https://community.nxp.com/t5/T-Series/Second-UART-on-T1024RDB/m-p/673817#M2045 int0dh 2017-08-09T05:25:21Z
