The Allwinner T113-s3 (sun8i) SoC features a dual-core Cortex-A7 ARM CPU and 128MB of DDR3 memory in the same physical package. It supports industrial temperature ranges. Most of the IP blocks are shared with the D1/D1s core. There are multiple variants of the SoC, which may vary in the included memory size, with some of them including a C906 RISC-V co-processor. Boards supported: - MangoPi MQDual T113 - wireless-only (RTL8723DS) - MYIR MYD-YT113 eMMC - 1Gbit ethernet (Motorcomm YT8531 PHY) - 4GByte eMMC - M.2-type slot for 4G/5G cards, plus 2x SIM slot - USB 2.0 ports - GPIO/I2C/SPI/CAN ports - FNLink 6131 (rtl8733bu) wifi module - MYIR MYD-YT113 SPI - Same as above but with 256Mbyte SPI-NAND flash instead of eMMC - Rongpin RP-T113 - 100Mbit ethernet (ICplus IP101GR PHY) - miniPCIe slot for 4G cards, plus 1x SIM slot - 3x USB 2.0 ports - RTL8723BS wireless - HYM8563 RTC - GPIO/I2C/SPI/CAN ports - Olimex T113-Olinuxino - 100Mbit ethernet (ICplus IP101GR) - UEXT connector (GPIO/I2C/SPI ports) - 1x USB 2.0 - audio jack, LEDC Installation: Use the standard sunxi installation to an SD-card.

Subject: [PATCH 4014/4018] sunxi: enable emac on Rongpin RP-T113
|
|
|
|
The emac is connected to an IC+ IP101 PHY, for which the driver
|
|
has been re-added (it was removed in 2014).
|
|
|
|
Currently the driver init fails with the below, so further tweaking
|
|
will be required.

|
|
|
CPU: Allwinner R528 (SUN8I)
|
|
Model: Rongpin RP-T113
|
|
DRAM: 128 MiB
|
|
Core: 36 devices, 15 uclasses, devicetree: separate
|
|
MMC: mmc@4020000: 0, mmc@4022000: 1
|
|
Loading Environment from FAT... Unable to read "uboot.env" from mmc0:1...

Net: eth_sun8i_emac ethernet@4500000: failed to get TX clock
|
