I'm wondering if this is still an issue. I was able to flash the spi on a recently built CURRENT (June and July). Fixed for me too (15.0-CURRENT). |
Overview Attempting to flash the SPI on the PINE RockPro64 results in an Input/Output error. Steps to Reproduce 1) dd if=/dev/zero of=/dev/flash/spi0 Actual Results dd reports an Input/Output error Expected Results The data should be written to the SPI.
