And this is definitely not good. Maybe something in the hardware has degraded and went bad? But you still can try to compile the mainline u-boot from git to check if the DRAM gets initialized and its size is reported correctly there. Some of the timing violations during the sunxi DRAM controller initialization had been fixed in the mainline u-boot. We may also need better error diagnostic messages. And tests on your hardware could help to improve this. > CPU: 960000000Hz, AXI/AHB/APB: 3/2/2 > spl: mmc init failed: err - -19 > ### ERROR ### Please RESET the board ### > > Other times it says: > > HELLO!

As you get sporadic BOOT0 boot messages, SD card also apparently sometimes fails. A common cause of this problem is a bit of dust in the SD card slot. Cleaning the SD card slot from dust and the electrical contacts of your SD card from grease may helps. -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
