Hi,
we have designed as system based on the Beaglebone Board.
We us Toshiba eMMC as system Flash memory.
Up to now we used the Toshiba 8GB THGBMHG6C1LBAIL, with that the system worked fine.
Now we upgraded to Toshiba 64GB THGBMHG9C4LBAIR, after initial boot system works fine, but after standby and wake up the eMMC flash many times is in read only mode and reports an error on the boot.
We have the Kernel V3.12 that was delivered by TI when we started development.
We enabled debugging what we are wondering is that the kernel send cmd 5 to set the Flash to sleep but for wakeup it does not send awake, there we see cmd 0 Reset and then CMD1 ask op condition.
After that some read requests are possible but when the kernel tries to write eMMC fails and is booting in read only mode.
Thanks for your support.
