cpu board 打件回來囉

0935

Boot Mode 設為 Serial Downloader 的時候, MfgTool 可以認到

Boot Mode 設為 Internal Boot, Boot Device 為 NAND 的時候
console 沒任何訊息

參考之前的紀錄 - morris NAND Flash issue

SW601{D1,D2,D3,D4} 原本為 {1,1,0,1} 改為 {1,0,0,1}

console 還是沒反應

0940

利用 MfgTool 來燒錄 code 吧

先參考 How-To use NAND boot on i.MX6UL EVK board 來試試看

首先我要有 u-boot.imx

參考 20160715_jeffrey

使用 bitbake u-boot-imx -c compile -f

得到 u-boot.imx

另存成 u-boot-imx6ulevk_nand.imx 放到

mfgtools\Profiles\Linux\OS Firmware\firmware\
mfgtools\Profiles\Linux\OS Firmware\files\

1050

參考 20160715_jeffrey

下載 imx6ul-14x14-evk-gpmi-weim.dts

放在 M300/fsl-release-bsp/build_small/tmp/work-shared/imx6ulevk/kernel-source/arch/arm/boot/dts/

在 M300/fsl-release-bsp/build_small/tmp/work-shared/imx6ulevk/kernel-source/

執行 make imx6ul-14x14-evk-gpmi-weim.dtb

得到 imx6ul-14x14-evk-gpmi-weim.dtb

在 <BUILD_DIR>/tmp/work/imx6ulevk-poky-linux-gnueabi/linux-imx/3.14.52-r0/build/arch/arm/boot/dts/

另存成 zImage-imx6ul-14x14-evk-gpmi-weim.dtb 放到

mfgtools\Profiles\Linux\OS Firmware\firmware\
mfgtools\Profiles\Linux\OS Firmware\files\

下載 mfgtool2-yocto-mx6ul-evk-nand.vbs

放到 mfgtools\

執行會出錯 - MfgTool.log

DLL version: 2.6.2
Wednesday, July 20, 2016 10:43:29   Start new logging

ModuleID[2] LevelID[1]: Parse ucl script failed, error code: 4

另存 ucl2.xml 為 ucl2.xml.original

修改 ucl2.xml - 一步一步確認

<UCL>
  ...
  <LIST name="NAND Flash" desc="Choose NAND as media">

    <CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>

    <CMD state="Updater" type="push" body="$ echo Update Complete!">Done</CMD>

  </LIST>

</UCL>

MfgTool 顯示 Jumping to OS image. 之後就停住了

M300 的 console 顯示如下

有得查了... 還不曉得錯在哪裡...

不管 SW601{D1,D2,D3,D4} 是 {1,1,0,1} 還是 {1,0,0,1} 結果都一樣

mail 給 FAE 先

1135

手上的 M300 CPU Board 編號是 1 號

從 morris 手上再拿個 3 號和 4 號試試

結果都一樣

1150

將 4 號板 Boot Mode 設為 Internal Boot, Boot Device 為 MicroSD

放入 SD Card, 開機

成功... 連 iCOS 都跑起來了

1305

先 review 早上發生的事

如果早上做的事換成用公板的 CPU Board 來試的話

發現就算沒有 NAND Flash 還是可以把 RAM 裡面的 kernel 帶起來

看一下 [U-Boot] MXS NAND: DMA read error

1510

剛剛 pioneer 分享 openvpn 在 vpn router 上的實作

porting 到 M300 的工作由 jammy 負責

不過我要幫忙一下 web page 和 cgi 的 porting 部分

1520

確定一些情報

mx6ul_14x14_evk.h 裡 CONFIG_SYS_USE_NAND 有被 define

繼續看 [U-Boot] MXS NAND: DMA read error

看了也不確定要改啥

啥 patch 說要改什麼向下面這樣的

/*
* NAND
*/
#define CONFIG_CMD_NAND
#define CONFIG_NAND_MXS
#define CONFIG_SYS_MAX_NAND_DEVICE	1
#define CONFIG_SYS_NAND_BASE		0x60000000
#define CONFIG_SYS_NAND_5_ADDR_CYCLE

目前 mx6ul_14x14_evk.h 相關部分如下

#ifdef CONFIG_SYS_USE_NAND
#define CONFIG_CMD_NAND
#define CONFIG_CMD_NAND_TRIMFFS

/* NAND stuff */
#define CONFIG_NAND_MXS
#define CONFIG_SYS_MAX_NAND_DEVICE	1
#define CONFIG_SYS_NAND_BASE		0x40000000
#define CONFIG_SYS_NAND_5_ADDR_CYCLE
#define CONFIG_SYS_NAND_ONFI_DETECTION

/* DMA stuff, needed for GPMI/MXS NAND support */
#define CONFIG_APBH_DMA
#define CONFIG_APBH_DMA_BURST
#define CONFIG_APBH_DMA_BURST8
#endif

既然說是 MXS NAND: DMA read error

那我就把 mx6ul_14x14_evk.h DMA 相關部分拿掉

#ifdef CONFIG_SYS_USE_NAND
...
/* DMA stuff, needed for GPMI/MXS NAND support */
#if 0
/* try to fix issue - MXS NAND: DMA read error */
#define CONFIG_APBH_DMA
#define CONFIG_APBH_DMA_BURST
#define CONFIG_APBH_DMA_BURST8
#endif
#endif

使用 bitbake u-boot-imx -c compile -vf

build 不過

看一下 log.do_compile.pid - 一堆 undefined reference

...

mxs_nand_read_buf

目前 M300 的 console 是公頭

兩個公頭之間先拿個杜邦線像下面的圖示連一下方便 jammy 繼續追 ethernet 的問題

1650

繼續

感覺不能只是單純的把 mx6ul_14x14_evk.h DMA 相關部分拿掉

出錯的點如下

<UBOOT_DIR>/drivers/mtd/nand/mxs_nand.c

/*
 * Read data from NAND.
 */
static void mxs_nand_read_buf(struct mtd_info *mtd, uint8_t *buf, int length)
{
    ...
    /* Execute the DMA chain. */
    ret = mxs_dma_go(channel);
    if (ret) {
        printf("MXS NAND: DMA read error\n");
        goto rtn;
    }
    ...
}
