Re: [meta-freescale] flexspi flashcp doesn't appear to work after moving from linux-fslc-imx 5.4.114 to 5.10.69 on imx8mm-evk board.

Hello,

I found my problem.  In the new imx8mm-evk.dts for 5.10.69 the flexspi node
has  spi-tx-bus-width = <1>; and in all the previous kernel versions
it was spi-tx-bus-width
= <4>;  so when moving our customized .dts over to new kernel that was
missed.

flashcp to our NOR and fw_setenv both work now.

Sorry for the noise.

Regards,

Brian
