In the same way, SPI0 is also wrong: SPI0 should be ALT3 and was incorrectly configured as ALT4, so these peripherals cannot work normally. The armbian version information for this error is as follows: | \ | | _ \(_) | \ | | ___ ___ | \| | |_) | | | \| |/ _ \/ _ \ | |\ | __/| | | |\ | __/ (_) | |_| \_|_| |_| |_| \_|\___|\___/ Welcome to Armbian 21.08.2 Focal with Linux 5.10.60-sunxi System load: 65% Up time: 0 min Memory usage: 15% of 491M IP: 192.168.4.107 CPU temp: 52°C Usage of /: 8% of 29G 0 Quote
chunjiu Posted October 1, 2021 Author Posted October 1, 2021 After finding Orange PI + 2E ( Same use H3 ), I verified that my judgment is correct, so is there any clue to solve this problem? 0 Quote
