@huali 在 host ECC nand flash怎么支持 中说：

.EccType = BIT4_LIMIT5_TO_8_ERR9_TO_15,
.EccProtectedType = SIZE512_OFF16_LEN4_OFF32,
.BadBlockFlag = BAD_BLK_FLAG_FIRST_2_PAGE,
.EccFlag、.EccType 、.EccProtectedType、.BadBlockFlag 该怎么写，谁有文档

改成
{
.Model = "MX35LF2G14AC",
.NandID = {0xc2, 0x20, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff},
.DieCntPerChip = 1,
.SectCntPerPage = 4,
.PageCntPerBlk = 64,
.BlkCntPerDie = 2048,
.OobSizePerPage = 64,
.OperationOpt = SPINAND_QUAD_READ | SPINAND_QUAD_PROGRAM |
SPINAND_DUAL_READ,
.MaxEraseTimes = 65000,
.EccFlag = HAS_EXT_ECC_SE01, // 需要外部ECC支持
.EccType = BIT4_LIMIT5_TO_7_ERR8_LIMIT_12, // 4位ECC能力
.EccProtectedType = SIZE16_OFF4_LEN8_OFF4, // 数据保护布局
.BadBlockFlag = BAD_BLK_FLAG_FIRST__PAGE,
},

报错：

回复: D1S的LEDC控制器可以走多少条LED灯总线？
PWM有点复杂，需要按0，1控制脉宽，不好搞
1、SPI方式mosi接灯带，但只能两条；
2、通过模拟开关，比如 3位控制8个开关，可以扩展ledc-do给八条灯带，注意开关断开的灯带，可能输入不确定， 不能浮空。
3、所有的灯带串在一起。有人测试1024个没有问题。

测试200个灯没问题；大于32个灯，驱动程序自动DMA传输，小于32，CPU传输
