--GxeWEYVLF0ONE7CmAnOi Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable I working on a custom IMX93 based board and having trouble working out exac= tly what is necessary to remap the UART from the default UART1 to UART3 (or= UART5). I've made a custom device tree with the nodes for the UART set to = "status =3D okay". But I'm not sure it works, as the UART5 seems to be muxe= d as an LCD controller (which we don't have and don't need). I deleted that= node, but I'm not certain the pins are in the correct state. Also, how doe= s one set the u-boot console to another UART? I've tried setting the consol= e environment variable: "setenv console ttpLP4" (UARTS start numbering at 1= , but the devices start at zero). From what I've found so far I may need to rebuild the spl too. --GxeWEYVLF0ONE7CmAnOi Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable <div>I working on a custom IMX93 based board and having trouble working out= exactly what is necessary to remap the UART from the default UART1 to UART= 3 (or UART5).
