It seems we've regressed with the Orange Pi PC for 2016.07 but I'm wondering with the PCSI bits whether the process has changed and I've missed the details of what's needed to flash u-boot.
With rc3 I see the follwing: U-Boot SPL 2016.07-rc3 (Jul 07 2016 - 10:36:40) DRAM: u MiB Could not determine boot source resetting ... But with 2016.05 GA I get: U-Boot SPL 2016.05 (May 30 2016 - 20:15:17) DRAM: 1024 MiB Trying to boot from MMC1 U-Boot 2016.05 (May 30 2016 - 20:15:17 +0000) Allwinner Technology CPU: Allwinner H3 (SUN8I 1680) Model: Xunlong Orange Pi PC I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: No ethernet found. starting USB...
