@smiletiger 唉我自问自答把
刚刚测试发现逻辑分析仪接错了clk线,测试出来是设置没有生效,时钟一直是100M

现在总结如下: t113s3的qspi其实没有想象中那么好,缺少一个qspi io模式,只有qspi in/qspi out模式,在时钟频率比较低的时候,qspi的确比spi快3-4倍,但是在时钟频率在100m以上的时候,qspi反而没有spi快,我测试下来读取15MB资料,在120M下面,qspi花时间1978ms spi花时间1973ms,应该是全志的qspi并不是完整的qspi导致的,所以优化开机启动的时候,用100M spi模式就可以,还可以省2个io口

使用命令mboot编译boot0和uboot已经成功,产生的文件四uboot.bin
想使用sunxi_fel uboot命令下载到ram调试提示

\u-boot.bin
Warning: no 'soc_sram_info' data for your SoC (id=1859)
SPL: eGON header is not found

spl头文件没有找到,应该用什么指令才可以产生包含spl的uboot呢,请教

有谁移植过t113或者f133的裸机G2D部分吗,我愿意出400元,有这方面经验的朋友可以私信我,谢谢

smiletiger

@chengwei_peng 哦,cpu读取的话占用cpu比较高,因为我用到的波特率是1.5Mbps,我在研究研究吧,只能曲线救国了

smiletiger

@yuzukitsuru 以前用的smt32之类的单片机都是一个个接收的啊,串口缓冲区有一个数据dma就传输一个,并不是这样128字节一起传输啊,这个你们有没有碰到过,串口比较特殊的,接收到的数据可能是不定长的,并不能事先设置固定的dma长度啊

smiletiger

@yuzukitsuru 我用的是裸机,我测试出来的结果就是用dma接收串口数据的时候,不是串口接收到一个dma就捕获一个,而是需要等到128字节,dma才会从串口获取128字节,当然如果我配置为dma长度为16字节,那么16字节就可以.

smiletiger

请问一下t113的dma是否有bug,我在测试uart3的rxd接收dma,配置为dma1,然后开始接收数据,比如我配置为接收256个字节产生dma完成中断,这个是没有问题的,并且也能正常接收到数据,但是想实现任意长度数据的接收,然后就想到读取dma寄存器的
0x0118 + N*0x0040 DMAC Channel Byte Counter Left Register N (Default Value: 0x0000_0000)这个寄存器,看资料这个寄存器里面读出来的数据就是代表本次dma传输剩余的数据,比如我上位机发送10个数据过去,然后这里应该读取出来的是(256-10)=246个,打是我在读取中发现这里的数据固定为256.....只有当上位机发送128个字节之后,这里的数据变成128 ,然后继续保持128不变,直到上位机发送完256个字节这里才变成0,
也就是说这个寄存器里面的数据是按照128字节跳跃的,并不是接收到多少个,这里减少多少个,是我配置的问题还是这个芯片本身的bug,

如果按照128字节跳跃的话,我该如何实现dma接收不定长数据的功能

smiletiger

@aozima dma可以用双核同时开启2个?那不是真的爽歪歪

smiletiger

https://bbs.aw-ol.com/topic/1543/发现一个t113-spi诡异问题?_=1654672907596

参考之前的帖子,然后现在加了dma测试了一下,读取10MB的时间为181ms,换算下来55MB/s
因为用的120M时钟,所以理论上是60MB每秒,比用cpu读取的快5倍

smiletiger

@secret 在 D1 裸机 DMA 中说：

dma_init

好像那个地址不需要高30位低2位互换
