一、BROM阶段 全志SoC有一个非常具体的启动过程。首先,它执行一个微小的片上 Boot ROM(BROM),然后检查按钮的FEL模式,然后开始检查各种存储选项的有效的引导签名在正确的位置。 上电后,SoC开始从BROM所在的地址0xffff0000获取指令。BROM分为两部分:第一部分(0xffff0000)是FEL模式,第二部分是eGON.BRM(位于0xffff400...

sunxi-fel version 正常,直接sunxi-fel uboot u-boot-sunxi-with-spl.bin下到ram中运行也是正常。但是spifalsh-write就一直出错,从没成功过。ERROR -1 -7 -8 -9都出现过。我装的双系统,在ubuntu和win10下现象一样,换台电脑现象也一样。我是淘宝上买的licheepi-nano,是不是我的板子主芯片坏了或者spi nor...
This adds the remaining code bits to teach U-Boot about Allwinner's newest SoC generation. This was introduced with the RISC-V based Allwinner D1 SoC, which actually shares a die with the ARM cores versions called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM). This adds...
由Soc 芯片原厂提供,通常 Soc 支持多少路 I2C 总线,就会有多少个硬件控制器,这些硬件控制器才是真正实现与外设芯片通信的地方。我们也可以通过 GPIO 模拟 I2C 时序来实现一个硬件适配器,对于设备驱动来说,它不需要关心 Soc 是通过何种方式产生通信时序来跟外设芯片通信的。

make target-tools builds tools that are intended for the target (Allwinner SoC), using a cross-compiler. The toolchain prefix CROSS_COMPILE defaults to arm-none-eabi-, adjust it if needed. Hint: When compiling 'natively' on the target platform you may simply use an empty toolchain prefix he...

So in my opinion, it is quite likely that this setting be moved upto the mmc-core level, for the SoC, rather then the card itself? Yes I was talking to Tsvetan from Olimex and he says they have seenthe problem with yetanother emmc, so this indeed seems to be a sunxi SoC specific...
