Write SPI Flash don't work

[t4_4t]

Good morning, this is morning.

I tried over 20 times on the conditions you presented.
However, we were unable to obtain a different result from the previous report.

I tried different things by changing the point of view.
I have two "ROCK64" units.
One is the one I used for the last time and the report this time, it is "ROCK64 (RAM-4G)"

I tried and checked with the other "ROCK64 (RAM-2G)"
With "ROCK64 (RAM-2G)", there was no problem even for cards with frequent errors.

I will write out the details of 2 cards I tried
Card-A) Silicon Power microSDHC 8GB Class10 with Adapter
Card-B) TOSHIBA EXCERIA UHS-I microSDHC 16GB class10

In order of card-grade, (including your card)
hi-grade             <->          lo-grade
Your-EVO >=  Card-B)  >  Card-A)    : Card Grade
 Crash             Many-Err      Good      : Result of "ROCK64"
Will be

From this, I guess that "cards with higher grade are more prone to problems."
However, it is not a problem of the card itself,
a problem with the "ROCK64" side including the driver.

The point that pointed out your log in the previous report means the above.
"Your-EVO" is "fall-back" to 25MHz after failure occurred at initialization.
This is "Card-A)" below, it is far below the performance of the original card.

And that is probably a problem on the "ROCK64" side, not doubting your card.
