Title: A20 buster sunxi-tools
Post by: andyw on September 16, 2020, 11:11:17 AM
I am using A20-OLinuXino-buster-base-20200701-173923.img

Looking in the latest A20-OLinuXino-Micro.pdf rev S March 2018 manual, page 15 states that you use chscr.sh and wrscr.sh to convert the fex files.

These are not present - is there an update to add these?

Thanks

Andy.

These tools are not available because there are no fex files in mainline images. They use overlays like these to describe the hardware:

If you wish to change some of the settings try the following scripts inside the image:

~#olinuxino-display – allows setting different video output;

~#olinuxino-overlay – provides easy way to enable or disable different hardware assignments – different I2C, SPI, UART, CAN, PWM, etc;

~#olinuxino-sd-to-emmc – allows booting from eMMC; transfers the Linux file system from the card to the eMMC memory (if your board has one); boot is placed in SPI flash memory;

~#olinuxino-sd-to-sata – allows booting from the SATA disk; transfers the Linux file system from the card to external SATA disk; boot is placed in SPI flash memory.
