I just rebased my tree on origin/master and got rid of my preliminary P2371 patches in favour of this only to notice that it doesn't work the way it used to. For example I used to use: # ums 0 mmc 1 to upload kernel, DTB and such to the external SD card. Unfortunately that no longer works with this version of the patches. I tried to see what the differences are but couldn't spot anything. I see that dmesg shows a bunch of USB device reset messages, and failures to read the superblock on /dev/sdc, which is what the mass storage shows up as. I also tried porting a couple of changes from my earlier tree over to master, but to no avail. Any ideas what could be the reason here? Does the external SD card work for anybody else? I also noticed two other things: > diff --git a/configs/p2371-0000_defconfig b/configs/p2371-0000_defconfig [...] > +CONFIG_USE_PRIVATE_LIBGCC=y Why do we need this? > diff --git a/include/configs/p2371-0000.h b/include/configs/p2371-0000.h [...] > +#define COUNTER_FREQUENCY 38400000 As far as I know the system counter is actually clocked by clk_m, which on most (all?) Tegra210 platforms will be configured to run at half the oscillator frequency (19.2 MHz). This is corroborated by the fact that running: # sleep 5 actually takes 10 seconds rather than the expected 5. Changing the above to 19200000 fixes that.
