Allwinner tech model qt 7 a33 processor11/5/2023 A prominent example is (the debug) UART0, which is on PortA on the H3, but on PortB on the A64. The pinmux configuration is still somewhat similar, but differs to an extent which makes them incompatible.The A64 has its BROM mapped at address 0, SRAM A1 is mapped right behind it at 0x10000 (64KB). The H3 has SRAM A1 mapped at address 0, the BROM is at 0xffff0000.The MMC clocks have changed on the way, now the MMC controller itself provides support for the output and sample phase. The MMC controller has been updated to support faster transfer modes.The H3 supports 5 UARTs, the A64 has 6 of them.Despite being a 64-bit chip, this makes the SoC entirely 32-bit on the physical side. The H3 DRAM controller supports up to 2GB of RAM, the A64 supports up to 3 GB.Both SoCs have an additional USB-OTG controller, which is assumed to be used as normal host controller as well.
