@yuzukitsuru 如果希望用xfel直接在ddr里引导Linux+rootfs，应该用您这里面哪个补丁？

T113现在有在DDR启动完整Linux的案例吗？posted in 编译和烧写问题专区
研究了好长时间，sunxi-fel有完整的教程但不支持T113，XFEL支持芯片，但卡在了引导阶段：
xboot：还没试。
awboot：初始化后只在flash和SD中尝试读取。
u-boot：目前用的100ask的sdk里编译出的u-boot-sun8iw20p1.bin，启动后显示如下U-Boot 2018.05 (Aug 04 2022 - 08:50:22 +0000) Allwinner Technology [2878.195]DRAM: 128 MiB [2878.199]Relocation Offset is: 04eee000 [2878.222]secure enable bit: 0 [2878.224]CPU=1008 MHz,PLL6=600 Mhz,AHB=200 Mhz, APB1=100Mhz MBus=300Mhz [2878.231]gic: normal mode [2878.234]flash init start [2878.236]workmode = 0,storage type = 0 sspi->base_addr = 0x4025000, the SPI control register: [VER] 0x4025000 = 0x00010001, [GCR] 0x4025004 = 0x00000083, [TCR] 0x4025008 = 0x00000184 [ICR] 0x4025010 = 0x00000f00, [ISR] 0x4025014 = 0x00000032, [FCR] 0x4025018 = 0x00200020 [FSR] 0x402501c = 0x00000000, [WCR] 0x4025020 = 0x00000000, [CCR] 0x4025024 = 0x00000002 [SDC] 0x4025028 = 0x00002000, [BCR] 0x4025030 = 0x00000000, [TCR] 0x4025034 = 0x00000000 [BCC] 0x4025038 = 0x00000000, [DMA] 0x4025088 = 0x000000e5 [2878.303]sunxi-spinand-phy: read id failed : -110 sspi->base_addr = 0x4025000, the SPI control register: [VER] 0x4025000 = 0x00010001, [GCR] 0x4025004 = 0x00000083, [TCR] 0x4025008 = 0x00000184 [ICR] 0x4025010 = 0x00000f00, [ISR] 0x4025014 = 0x00000032, [FCR] 0x4025018 = 0x00200020 [FSR] 0x402501c = 0x00000000, [WCR] 0x4025020 = 0x00000000, [CCR] 0x4025024 = 0x00000002 [SDC] 0x4025028 = 0x00002000, [BCR] 0x4025030 = 0x00000000, [TCR] 0x4025034 = 0x00000000 [BCC] 0x4025038 = 0x00000000, [DMA] 0x4025088 = 0x000000e5 [2878.371]sunxi-spinand-phy: read id failed : -110 initcall sequence 47f89454 failed at call 4300f0f5 (err=-1) ### ERROR ### Please RESET the board ###https://linux-sunxi.org/FEL/USBBoot 提供的方案似乎并不适用于xfel。
