Part Number:AM4378
Tool/software: Linux
Hi,
I have gumstix poblano board with am4378 and it looks like it cannot enter to peripheral boot mode (printing CCCC on serial console and image can be sent over UART). I read about similar issue: 
but errata shows that UART peripheral boot is broken only on rev. 1.1 (while is I decoded it correctly I have revision 1.2): AM4378BZDNI00. Is there some other problem or do I need to do something else to enter this mode? Thanks.
