自己设计了一块hi3556v200 spinand的开发板，目前配置启动参数后可以起来，但是virt-tty打不开，不知道是参数不对导致liteos没有起来还是怎么的，有了解的兄弟帮忙分析下，谢谢! 启动参数如下： setenv bootargs 'mem=64M console=ttyAMA0,115200 root=/dev/mtdblock5 rootfstype=yaffs2 mtdparts=hinand:1M(u-boot.bin),1M(rawparam),1M(rawparambak),8M(media_app_zip.bin),5M(uImage),12M(rootfs.yaffs),30M(appfs.yaffs)' setenv bootcmd 'nand read 0x83b00000 0x300000 0x800000;go_cpu1 0x83b00000;nand read 0x82000000 0xb00000 0x500000;bootm 0x82000000';sa 下面一个也试过不行： setenv bootcmd 'go_cpu1 0x87400000 0x83b00000 0x300000 0x800000;nand read 0x82000000 0xb00000 0x500000;bootm 0x82000000';sa

本帖最后由 qn1530868394 于 2019-8-11 12:59 编辑 大家好，现在自己设计一块hi3516a的板子，接imx385，然后385按fae给的驱动配置起来，示波器量sensor端信号看起来是正常的，mipi这块也采集到数据，然后vi看起来也正常，但是编码存储下来的图像全黑的，有没有朋友碰到过这种情况，有经验的能否帮忙指点下怎么定位问题在哪里？ 示波器量的信号分别为hi3516给出的时钟，mipi时钟，帧信号，行信号; 截图的信号为：mipi，vi，venc。

自己设计的板子，spi nor flash能烧写成功，uboot能正常起来，spi nand flash 烧写报错，spi nor和spi nand都是8pin的，有没有朋友碰到的？能帮忙分析下吗？试的几个flash都是表里支持的：TC58CVG0S3H RAIF  PN26G01AWSIUG  GD5F1GQ4UBYIG Boot downloading started.

有没有接过的指导下，加载驱动./load3519av100 -i -sensor0 bt656 在调用s32Ret = HI_MPI_VI_CreatePipe(ViPipe, &stPipeAttr);时报如下错误： [SAMPLE_COMM_VI_StartViPipe]-2105: 222  HI_MPI_VI_CreatePipe failed with 0xa0108003! pipe的参数配置如下： VI_PIPE_ATTR_S PIPE_ATTR_BT656D1_1MUX = {             /* bBindDev bYuvSkip */     VI_PIPE_BYPASS_NONE, HI_FALSE,HI_TRUE,     720, 576,     PIXEL_FORMAT_YUV_SEMIPLANAR_422,     COMPRESS_MODE_NONE,     DATA_BITWIDTH_8,     HI_FALSE,     {         PIXEL_FORMAT_YUV_SEMIPLANAR_422,         DATA_BITWIDTH_8,         VI_NR_REF_FROM_RFR,         COMPRESS_MODE_NONE     },     HI_FALSE,     { -1, -1},     HI_FALSE }; 发现PIXEL_FORMAT_E  enPixFmt只能配置为rgb，HI_BOOL bIspBypass配置为HI_FALSE时才能成功配置下去，按手册理解PIXEL_FORMAT_E  enPixFm应该配置为yuv，HI_BOOL bIspBypass配置为HI_TRUE，就会报上面的错误。 还有VI_DEV_ATTR_S DEV_ATTR_BT656D1_1MUX = {     VI_MODE_BT656,     VI_WORK_MODE_1Multiplex,     {0xFFF00000,    0x0},     VI_SCAN_PROGRESSIVE,     {-1, -1, -1, -1},     VI_DATA_SEQ_YUYV,      .......} VI_SCAN_MODE_E      enScanMode;参数只能配置为逐行，配置为隔行也配置不下去。 不知道是我配置的有问题，还是hi3519av100的驱动支持有问题，有没有调试过这块的指导下，在hi3519v101上接入是成功的。

目前有个i2c设备，需要分两次写10个字节过去，然后读18个字节数据，写没有问题，我在应用层用ioctl去读，和内核级用i2c_master_recv接口函数去读，都出现hisi-i2c-v110 12112000.i2c: Unsupported read-only!错误，看了tlv320aic31的驱动，他读是调用ret = i2c_transfer(client.adapter, msg, 2);只是2字节，hisi3519v101到底支持多字节多写不？ 请问下大家有没有做出来能连续读多字节的？难道只能用gpio模拟？

我在内核加了一个外设驱动，然后调用i2c去配置（内核级），出现如下报错： in __I2CWriteByte8: 60 ff 0 hisi-i2c-v110 12112000.i2c: hi_i2c_wait_idle: wait last fifo is empyt abort! hisi-i2c-v110 12112000.i2c: RI: 0x750 hisi-i2c-v110 12112000.i2c: TX_ABRT:0x1 in __I2CReadByte8: 60 f4 hisi-i2c-v110 12112000.i2c: Unsupported this length: 1! hisi-i2c-v110 12112000.i2c: Unsupported read-only! 有没有朋友碰到这个现象解决了的？

按Hi3519V101／Hi3516AV200 SDK 安装以及升级使用说明.txt文档编译烧写到nand flash，板子起来后,报如下错误： VFS: Cannot open root device "mtdblock2" or unknown-block(0,0): error -6 有没有碰到这种情况的？ 详细串口打印如下： U-Boot 2010.06 (Jul 10 2018 - 15:19:43) Check Flash Memory Controller v100 ...

flash为spi nand ，系统起来后，如何通过linux命令擦除块，然后把升级文件烧写上去，我按如下方式操作没有成功: flash_erase /dev/mtd4 0 448 nandwrite -p -s 0 /dev/mtd4 /mnt/upgrade/hisi/hi3516dv300/target/pub/user_V15.0.1_YJ310_VVXnn5.yaffs2 mount -t yaffs2 /dev/mtdblock4 /mnt/user 想法是把mtd4擦除，然后把yaffs2写进去，再mount，结果里面就一个lost+found 啥也没有，有没有朋友弄过的，给指点下。
