I've figured out a way to repeat this on my machine.
If I write 0xff's to the eMMC blocks, then issue an erase for the same, I get the problem with each MMC_ERASE command.
I've also found something that fixes the issue in my testing.
Changing SECURE_ERASE to 0 from 0x80000000 in include/mmc.h allows things to function for me.
Page 115 of the JEDEC eMMC 4.5 spec says that bit 31 is obsolete and should be zero: http://www.jedec.org/sites/default/files/docs/jesd84-B45.pdf
Hector and Fabio, can you test that change?
Managed to get access to a revC2 board and tested your change.
I am happy to say that 'mmc erase' works now :-)
Glad to hear it.
Good job, Eric!
When you send a formal patch then you can add:
