32 KB I-cache + 32 KB D-cache
Allwinner D1s (also known as F133) is based on a RISC-V core, and is a cheaper version of the D1 with the following differences:
- 64 MB of DDR2 memory included in the same package, instead of requiring external memory.
- No Tensilica HiFi4 DSP.
- No HDMI output.
One less I2S port.
After Flash
After flashing is complete, you can eject the TF card and insert it into the TF card slot (black font serial number 11) on the front of the development board. At this point, you can:
- Use Dupont wires to connect PE2, PE3, and GND for serial login
- Or use adb shell to connect directly via ADB for login access - adb-dat
Note: On the D1s, since the TF card and CKlink pins are multiplexed, you need to set the DIP switch SW1 to the numeric direction to support TF card boot
