uSD boot

Former Member

Dear all,

I have flashed SVN3000 image to an SD card. When I boot it from SD connector (J6, bottom) it works perfectly, however, when I boot the riotboard from uSD (J7, top) image stored in eMMC is booted.

I have checked a hundred times the boot switches and it is correct:

                         D1 D2 D3 D4 D5 D6 D7 D8

SD (J6, bottom)    1   0   1    0    0    1    0    1

uSD (J7, top)        1   0   1    0    0    1    1    0

 

could you please give me any advice?

 

Thank you in advance!

    I have found the solution by chance ... after having written my question. This is what I have done, just in case somebody else has the same problem:

    I read somewhere: "if you use a MicroSD, make sure to change boot script to use device 1 instead of 0" and this is what I have done:

    In u-boot I have written:

    > setenv mmcdev 1

    > saveenv

    change the switches, insert the sd in the usd connector and restart.
