When will you release new firmware fixing problem of SPI?
-
I sent 2 bytes, 0x7f 0x79, through SPI, using spi-tool in command line.
spi-tool -b 1 -d 32766 write 0x7f 0x79
I read values from spi bus using logic analyzer. The actual bytes sent are 0xff 0x79.
I tried to analyse why and when this happen. I found if the first byte, normally register address, equal or larger than 0x40, then the most significant bit become 1.
For example, 0x40 becomes 0xc0, 0x7f become 0xff.
I asked for a long time, waiting fix for a long time.
NO ANSWER, NO REPLY, seems there is no problem of SPI.
WHY?
This is a board for IoT, for many usages. How could you just leave this problem for such a long time?

Hi Max
There is already a discussion going on regarding a severe SPI bug.
Please see https://community.onion.io/topic/1560/spi-pins-for-the-omega2Cheers

I read that discussion months ago.
The last message was 5 months ago.
It's only 'issue need to be fixed', 'somebody has temporary testing fixing lib'...etc.
There is no official fix or update from Onion.
I don't think it's a solution for normal users.
