qinlinbin 发布的帖子

楼主请问一下你这个问题解决了吗？

@awwwwa 你好。这两种设备树的485定义，我在5.4内核和5.10内核中都没有找到响应的定义，请问这是在哪个驱动代码里面实现的呢？我在a40-i的5.10内核，甚至没有找到sunxi-uart.c这个文件，这个正常吗？

@ppatb01 https://github.com/mangopi-sbc/aw-doc/tree/main/tina-doc

请问一下，你这个问题解决了吗

@codedogejack123 没有，只是把DMA_SERIAL_BUFFER_SIZE改成了2k，凑合着使用。假如你有解决方法，麻烦分享一下。

大佬，想问一下，你有测试过80k以下波特率的吗？我试了一下，会报这个错误。
ip link set can0 type can bitrate 50000
sunxi_can 2504000.can can0: bitrate error 8589934.5% too high。你有遇到过吗？

@lvjun0728 你好，你在t113上使用的ncm方式的操作方法能分享一下吗

@maihuanyi udc dma（sunxi_udc.c)相关的有bug，问问供应商或者论坛大佬要要补丁。

@maihuanyi 没有，没去折腾这个了。您解决了话，烦请开个帖子说一下解决方法

@daizebin 好的，非常感谢

@daizebin 好的，非常感谢。再请教一下，这个开源物料补丁是什么东西呢

@whycan 晕哥，w25n02的参数配置，能发一下吗

@whycanservice 我对比了正常的flash芯片（支持列表里面的），这里也是会打印这个log，到了打印“SPI nand ID: 22aaef 0”之后，log才不一样。我看晕哥在其它帖子上说d1s/d1h支持了W25N02，那这个配置参数能发一下吗？

我在R328-S2上使用W25N02KVZEIR，在uboot-id.c文件添加这个器件的支持，但是烧录的时候失败了。

请教一下各位大佬，这是什么问题呢？id.c上的配置信息这样填写正确吗？

@ddrddr 大佬，这里你是把这一行注释掉吗？还是说做了其它判断？

@qinlinbin （挖个坟），难道没人遇到这个问题吗

大佬，我想问问，kernel阶段串口有输出，但是boot0和uboot阶段没输出，这是哪里没配置好呢

@aozima 我在设备树把其它外设的dma关掉了，看了一下，应该是够了的

t113-s3开启一个串口的dma，使用正常。但是开启了2个或以上的串口dma的时候，就会报以下错误

[ 30.010846] sun6i-dma 3002000.dma-controller: Failed to alloc lli memory

还有就是不开dma的时候，串口在460800及以上波特率就容易丢包，有oe产生。
请问一下，有谁遇到过这些问题吗？可以怎么解决呢？

@zhangwei 这个似乎还要make menuconfig-kernel feature，把相应的内核模块选中（选*）。

@yuzukitsuru 大佬，那这个问题修复了吗

请教一下各位，t113-s3，开启rndis的时候，可以正常ssh，但是通过scp发送文件的时候，就会出现kernel panic，然后卡死。日志如下。请问有谁遇到过吗？大概是什么问题？可以怎么解决？

@steelen 楼主，你好。我最近调rtl8821cs的蓝牙。发现开了流控，下载固件的时候就会通讯失败。关了流控就好了。想请教一下，你这个问题解决了吗

@whycanservice 时序参数问了屏幕厂家，也没有。相位调了一下没变化。之前是用stm32的fsmc驱动的。发现有rgb，所以看看用t113看能不能驱动。资料太少，还是放弃了。已买其它屏幕。谢谢了。

请教各位大佬，你们调试屏幕的时候有出现过图片这个情况吗？这是colorbar显示的效果，其它图片的话就是花屏。这大概是哪里的问题？

另外用逻辑分析仪录得de dclk hsync vsync 的波形，




这是不是这几个时钟完全不对？

@jr_online 安装bison

问个题外的，楼主你的触摸屏的延长线哪里买的

@whycan 晕哥，你推荐的这个5寸屏幕，lcd的设备树参数可以参考哪里的呢

@yuzukitsuru 看漏了，谢谢大佬

想问一下，你第一次发的和第二次发的有什么区别呢？我看了一下，配置好像不一样？

@q1215200171 好的，谢谢

@q1215200171 你好，请教一下，这个是uboot的代码还是内核的代码呢？t113支持吗

@fenglichaoa 这个rootfs是不是打包成squashfs格式的？是的话，

@yy_fly 这个问题需要你自己研究一下了

@yy_fly 仅供参考！！！spi-sunxi.c文件。

/* reset fifo */
static void spi_reset_fifo(void __iomem *base_addr)
{
	u32 reg_val = readl(base_addr + SPI_FIFO_CTL_REG);
	u32 poll_time = 0x7ffffff;
	reg_val |= (SPI_FIFO_CTL_RX_RST|SPI_FIFO_CTL_TX_RST);
	/* Set the trigger level of RxFIFO/TxFIFO. */
	reg_val &= ~(SPI_FIFO_CTL_RX_LEVEL|SPI_FIFO_CTL_TX_LEVEL);
	reg_val |= (0x20<<16) | 0x20;
	writel(reg_val, base_addr + SPI_FIFO_CTL_REG);

        /*添加的内容*/
	reg_val = 0;
	reg_val = readl(base_addr + SPI_FIFO_CTL_REG);
	while((reg_val & SPI_FIFO_CTL_RX_RST || reg_val & SPI_FIFO_CTL_TX_RST) &&
			--poll_time)
		reg_val = readl(base_addr + SPI_FIFO_CTL_REG);
}

static int sunxi_spi_cpu_readl(struct spi_device *spi, struct spi_transfer *t)
{
	struct sunxi_spi *sspi = spi_master_get_devdata(spi->master);
	void __iomem *base_addr = sspi->base_addr;
	unsigned rx_len = t->len;	/* number of bytes sent */
	unsigned char *rx_buf = (unsigned char *)t->rx_buf;
	unsigned int poll_time = 0x7ffffff;
	unsigned int i, j;
	u8 buf[64], cnt = 0;

	while (rx_len && (--poll_time > 0)) {
	/* rxFIFO counter */
		if (spi_query_rxfifo(base_addr)) {
			*rx_buf++ =  readb(base_addr + SPI_RXDATA_REG);
			--rx_len;
		}
	}
        /*余下的没改*/
}

spi我也遇到过卡死的问题，不是这个大佬的代码，是代理给的代码。resetfifo后，没等reset结束，直接读数据，就会卡死。我把它改成resetfifo后，判断一下reset完成再进行下一步就不会卡死了。

挖个坟？dma接收不定长数据的功能，需要配合timeout来完成。楼主看试试能不能行

@yuzukitsuru 谢谢大佬。还有个报错，知道是什么问题吗？

有哪位大佬遇到过吗？有什么解决的办法吗？

@yuzukitsuru 谢谢大佬。再请教一下，出现这个报错的情况，是将一个分区的文件，解压到另一个分区的时候出现的，两个分区都是fat格式的。储存用的是mmc，这个brcmfxxx是WiFi的驱动。大佬有解决思路或者调试方向可以指引一下吗

你好，我想问一下。使用新的dtb，那sys_package.cfg要把dtb项去掉吗？

t113运行某些程序的时候，会出现如下报错，想请教一下各位大佬，这个是什么原因引起的报错

这个问题之前也遇到过。就普通的按键，有时候会失灵。修改采样时钟为24m就没问题了。配置的上升沿和下降沿触发，难道需要捕获到上升沿和下降沿才会触发中断吗？

longon的sdk，也遇到过经常reboot卡死，主要是在充电发热的时候，后面把psci.c里面psci_sys_reset函数的else里面的屏蔽掉，然后就会执行看门狗重启，就不会卡死。也不知道什么问题。

@honey130602 楼主，你的问题解决了吗？修改调试串口需要改那些文件呢，求教

想问一下楼主，你的板子和屏幕是哪里买的呢？有链接吗
