移植MT7620A+MT7610E驱动到Openwrt trunk(Linux Kernel 3.14.18)(续:MT7620A)

按照上一篇的内容修改文件重新编译后不会报错,但是烧到flash里后运行的时候有问题,如下:

解决方法:

移植7620

1. 添加os/linux/rt_flash.c 内容为:

#include <linux/module.h>#include <linux/types.h>#include <linux/init.h>#include <linux/kernel.h>#include <linux/version.h>#include <linux/err.h>#include <linux/slab.h>#include <linux/delay.h>#include <linux/sched.h>#include <linux/backing-dev.h>#include <linux/compat.h>#include <linux/mount.h>#include <linux/mtd/mtd.h>#include <linux/mtd/map.h>#include <linux/mtd/concat.h>#include <linux/mtd/partitions.h>struct proc_dir_entry *procRegDir;/* * Flash API: ra_mtd_read, ra_mtd_write * Arguments: *   - num: specific the mtd number *   - to/from: the offset to read from or written to *   - len: length *   - buf: data to be read/written * Returns: *   - return -errno if failed *   - return the number of bytes read/written if successed */int ra_mtd_write_nm(char *name, loff_t to, size_t len, const u_char *buf){    int ret = -1;    size_t rdlen, wrlen;    struct mtd_info *mtd;    struct erase_info ei;    u_char *bak = NULL;    mtd = get_mtd_device_nm(name);    if (IS_ERR(mtd)) {        ret = (int)mtd;        goto out;    }    if (len > mtd->erasesize) {        put_mtd_device(mtd);        ret = -E2BIG;        goto out;    }    bak = kzalloc(mtd->erasesize, GFP_KERNEL);    if (bak == NULL) {        put_mtd_device(mtd);        ret = -ENOMEM;        goto out;    }#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,3,0)    ret = mtd_read(mtd, 0, mtd->erasesize, &rdlen, bak);#else    ret = mtd->read(mtd, 0, mtd->erasesize, &rdlen, bak);#endif    if (ret) {        goto free_out;    }    if (rdlen != mtd->erasesize)        printk("warning: ra_mtd_write_nm: rdlen is not equal to erasesize\n");    memcpy(bak + to, buf, len);    ei.mtd = mtd;    ei.callback = NULL;    ei.addr = 0;    ei.len = mtd->erasesize;    ei.priv = 0;#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,3,0)    ret = mtd_erase(mtd, &ei);#else    ret = mtd->erase(mtd, &ei);#endif    if (ret != 0)        goto free_out;#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,3,0)    ret = mtd_write(mtd, 0, mtd->erasesize, &wrlen, bak);#else    ret = mtd->write(mtd, 0, mtd->erasesize, &wrlen, bak);#endif    udelay(10); /* add delay after write */free_out:    if (mtd)        put_mtd_device(mtd);    if (bak)        kfree(bak);out:    return ret;}int ra_mtd_read_nm(char *name, loff_t from, size_t len, u_char *buf){    int ret;    size_t rdlen = 0;    struct mtd_info *mtd;    mtd = get_mtd_device_nm(name);    if (IS_ERR(mtd))        return (int)mtd;#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,3,0)    ret = mtd_read(mtd, from, len, &rdlen, buf);#else    ret = mtd->read(mtd, from, len, &rdlen, buf);#endif    if (rdlen != len)        printk("warning: ra_mtd_read_nm: rdlen is not equal to len\n");    put_mtd_device(mtd);    return ret;}EXPORT_SYMBOL(ra_mtd_write_nm);EXPORT_SYMBOL(ra_mtd_read_nm);EXPORT_SYMBOL(procRegDir);MODULE_AUTHOR("Steven Liu <steven_liu@ralinktech.com.tw>");MODULE_DESCRIPTION("Ralink APSoC Flash Map");MODULE_LICENSE("GPL");

2. 修改os/linux/rt_proc.c

struct proc_dir_entry *procRegDir

 改为:

struct proc_dir_entry *procRegDir2860v2

并将该文件中所有调用procRegDir 的地方改为: procRegDir2860v2

 

3. 在Makefile中添加

rt2860v2_ap-objs += ../rt2860v2/os/linux/rt_flash.o


4. 修改 include/chip/rt2880.h
将:

#include <asm/rt2880/rt_mmap.h> 

改为: 

#include "rt_mmap.h" //fix

5. 修改 include/iface/rtmp_rbs.h

将:

#define RTMP_MAC_IRQ_NUM    4

 改为 

#define RTMP_MAC_IRQ_NUM    6

6. 修改 include/video.h

添加 

VOID VideoTurbineDynamicTune(IN PRTMP_ADAPTER pAd);
