Week 7 (25 July - 1 Aug)

• Closed Following Issues:
  • #10
  • #7
  • #8
• Added Helper scripts for dtc, spi flash.
• Explored way to tristate SPI pins without adding overlay for it.
• Adding Litex with gpmc to wishbone wrapper.

On-going blockers:

• In beaglewire we had three dtc files as of now:
  1. overlay with spi enabled.
  2. overlay with spi tristated (0x37) (we wanted to tristate spi so that it doesn't interfer with fpga)
  3. overlay with ice40 on spi.
• I wanted to change the pin mode of the pins in run time to avoid changing overlay and reboot process.
• config-pin utility requires the enable universal overlay which causes lots of pinmux issue with gpmc that we are using in beaglewire. So wanted some other way to change pinmode.
