Hi Sir,
My customer need I.MX8QX SPI0_MOSI default low for communicate to SPI device.
I try to modify pad/mux control register from kernel dts file as below . But the MOSI pin default always is high. (Besides open-drain) .
How can I set MOSI pin default low ? Thanks~
26-25(SW CONFIG) 6-5(pull) MOSI status
00b-DEFAULT 10b-pull down High
01b-OPEN-DRAIN 10b-pull down Always Low
10b-OPEN-DRAIN-INPUT 10b-pull down High
11b-INOUT 10b-pull down High
Hi Jimmy
using dts settings it is not possible to set default pin value.
In general if spi module settings allows for such default configuration, it
can be done in uboot.
Best regards
igor
