I'm unable to get the USB Mass Storage thing to work on my Mac, or my Ubuntu 14.04 VM. It's the little port, right, the mini-USB connector? Anyway, when I interrupt U-Boot, I did this:
> => setenv umsmedia 0; gpio set 53; run findfdt; setenv mmcdev 1; setenv > bootpart 1:1; run mmcboot > > FAILSAFE: U-Boot UMS (USB Mass Storage) enabled, media now available over the > usb slave port ... > UMS: disk start sector: 0x0, count: 0x734000 > musb-hdrc: peripheral reset irq lost! When I connect my Mac to the small port, the Mac reports a USB download gadget, not a mass storage device. When I try to connect that to the Linux VM, I don't see anything (but don't know where to look). Alternatively, how do I change the dyndbg setting that U-Boot is loading? The problem: I updated my uEnv.txt to turn on more debugging output, and I think it hosed part of the boot process, which times out now (it just repeats the last bit over and over): > Loading, please wait... > fsck from util-linux 2.25.2 > BEAGLEBONE: recovering journal > BEAGLEBONE: clean, 43481/236176 files, 285892/943872 blocks > [ 9.931380] rtlwifi: Firmware rtlwifi/rtl8192cufw_TMSC.bin not available > [ 10.860147] libphy: PHY 4a101000.mdio:01 not found > [ 10.864972] net eth0: phy 4a101000.mdio:01 not found on slave 1 > Starting Journal Service... > [ TIME ] Timed out waiting for device dev-ttyGS0.device. > [ 95.707797] systemd[1]: Timed out waiting for device dev-ttyGS0.device. > [DEPEND] Dependency failed for Serial Getty on ttyGS0. > [ 95.727835] systemd[1]: Dependency failed for Serial Getty on ttyGS0. > Starting Journal Service... > [ OK ] Stopped Trigger Flushing of Journal to Persistent Storage. > Stopping Journal Service... > [ OK ] Stopped Journal Service. > Starting Journal Service... > [ OK ] Started Journal Service. > Starting Trigger Flushing of Journal to Persistent Storage... > [ OK ] Started Trigger Flushing of Journal to Persistent Storage. > [ *** ] A start job is running for LSB: Raise network interf...13s / no > limit) These variables don't seem to be loaded into the environment, and I don't see an obvious command for adjusting them: > Running uname_boot ... > loading /boot/vmlinuz-4.1.4-ti-r9 ... > 8259336 bytes read in 473 ms (16.7 MiB/s) > loading /boot/dtbs/4.1.4-ti-r9/am335x-boneblack-emmc-overlay.dtb ... > 55644 bytes read in 28 ms (1.9 MiB/s) > loading /boot/initrd.img-4.1.4-ti-r9 ... > 4496957 bytes read in 272 ms (15.8 MiB/s) > > debug: [console=ttyO0,115200n8 dyndbg=file drivers/of* +pflm; file > drivers/i2c* +pflm; file drivers/remoteproc +pflm; file sound* +pflm; file > pinctrl/* +pflm; file drivers/gpio/* +pflm; file drivers/regulator* +pflm; > file *cape* +pflm root=UUID=69f859b1-c308-41c9-8ca7-a3d0042031e8 ro > rootfstype=ext4 rootwait fixrtc coherent_pool=1M quiet] ... > > debug: [bootz 0x82000000 0x88080000:449e3d 0x88000000] ...
