Informational resources

Here are links to various external resources with information about the Mango Pi, RISC-V assembly, C, and more.

Mango Pi

• Manufacturer's site Mango Pi MQPro https://mangopi.org/mqpro
• Mango Pi schematic readings/mq-pro-sch-v12.pdf
• Interactive tour of Mango Pi board https://mangopi.org/_media/mq-pro-v12-ibom.html
• The Mango Pi uses an Allwinner D1-H chip. The peripherals are documented in the Allwinner D1-H User Manual
  • The user manual is 1400 pages of nitty-gritty goodness (addresses, layouts, behaviors). It's a tome for sure, but keep this one bookmarked, you'll be looking at it often.
• The D1 has a single RV64GCV core XuanTie C906 made by T-Head Semiconductors.
  • Processor overview https://www.riscfive.com/2023/03/09/t-head-xuantie-c906-risc-v/
  • Full documentation XuanTie-Openc906-UserManual

RISC-V architecture

• The Risc-V Reader: An Open Architecture Atlas, Patterson & Waterman https://www.amazon.com/dp/0999249118/
  • Amazingly succinct yet thorough coverage of the architecture, with backstory on how the design came to be.
