Please test this branch: https://github.com/lmajewski/u-boot/commits/phycore-imx8mm-qspi-nvme On HOST: uuu -v -b qspi ~/work/DENX/u-boot/flash.bin Stop on u-boot prompt. u-boot=> fastboot 0 QSPI is flashed via USB - however - I've noticed that there are some flipped bits on USB transmission when I do compare it with tftp transfer. This needs to be investigated, however seems to be an orthogonal problem from QSPI boot support. > > Log on target: > > U-Boot SPL 2024.10-rc2-00131-g0303f2240376 (Aug 19 2024 - 15:18:36 > +0200) WDT: Started watchdog@30280000 with servicing every 1000ms > (60s timeout) Trying to boot from USB SDP > > U-Boot SPL 2024.10-rc2-00131-g0303f2240376 (Aug 19 2024 - 15:18:36 > +0200) WDT: Started watchdog@30280000 with servicing every 1000ms > (60s timeout) Trying to boot from USB SDP > > To me it looks like there are some changes missing to get this > feature to work. > You can take a look at my commits where I added this feature for > imx8mp. 199229e28b2b2da57c52ee46452f930785cf6002 ("phycore-imx8mp: > add USB mass storage support") > 8dcf1df48dff339b172d1bce2a38a965ee4aafca ("phycore-imx8mp: add > support for booting and flashing emmc via UUU") > > > Here are the changes I needed to do on top of your patch to get this > feature to work for mini: > > diff --git a/arch/arm/dts/imx8mm-phyboard-polis-rdk-u-boot.dtsi > b/arch/arm/dts/imx8mm-phyboard-polis-rdk-u-boot.dtsi > index 516e52e1f5de..cdaff2f8da9b 100644 > --- a/arch/arm/dts/imx8mm-phyboard-polis-rdk-u-boot.dtsi > +++ b/arch/arm/dts/imx8mm-phyboard-polis-rdk-u-boot.dtsi > @@ -69,3 +69,8 @@ > &wdog1 { > bootph-pre-ram; > }; > + > +&usbotg1 { > + dr_mode = "peripheral"; > + u-boot,dm-spl; > +}; > diff --git a/board/phytec/phycore_imx8mm/phycore-imx8mm.c > b/board/phytec/phycore_imx8mm/phycore-imx8mm.c > index 06cffbca3a69..00fdd4edbe36 100644 > --- a/board/phytec/phycore_imx8mm/phycore-imx8mm.c > +++ b/board/phytec/phycore_imx8mm/phycore-imx8mm.c > @@ -45,6 +45,10 @@ int board_late_init(void) > case MMC3_BOOT: > env_set_ulong("mmcdev", 2); > break; > + case USB_BOOT: > + printf("Detect USB boot.
