Hello Everyone! Thanks for all your excellent work on AllWinner processors. Thanks to your work, I have been able to do interesting things with the CubieBoards I have.
I have recently received an AllWinner A20 based device. I've been following the steps detailed in http://linux-sunxi.org/New_Device_howto and http://linux-sunxi.org/Retrieving_device_information. This device does not have a USB OTG port. It also does not run Android. It runs a custom version of Linux that provides no console over UART or the graphical terminal. I was able to get the device into FEL mode by holding down '2' over the serial console, but since there isn't an OTG port, I haven't been able to retrieve any data. The device does have a microSD port, but I do not have a LiveSuite image. I tried booting with the premade Debian SD Card image for CubieBoard2 from http://ftp.uk.debian.org/debian/dists/stretch/main/installer-armhf/current/images/netboot/SD-card-images/, but that obviously didn't work. I see this in a loop over the serial console: U-Boot SPL 2016.05-armbian (Jun 21 2016 - 17:45:38) DRAM: 512 MiB Failed to set core voltage! Can't set CPU frequency Could not determine boot source resetting ... I am loath to desolder the NAND chip and directly read its contents. Is there any other way I can retrieve device information? If I were to desolder and read the NAND chip, what would be a good flash reading toolkit to use and howto to follow. This chip is a Hynix H27UBG8T2CTR, and it looks like a TSOP48 to me. Thanks so much for looking at my post. Saurabh -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
