Hi Anand,
I tried a few sdcards on the OC2 with your 2 patches.
Like with the libretech-cc, sdr104@200Mhz works "mostly", but, with some
sdcards, it does not - please see below. The same sdcards appear to be working
fine on my laptop.
This is something I have not been able to crack yet on the libretech-cc.
I'd suggest dropping sdr104 and keeping the max frequency at 100Mhz until we can
figure out the problem here.
With this changed:
