无法打开目录后卸载USB会导致一般异常处理程序

将USB代码与Hyv1.V11进行比较，看看是否能发现任何更改。如果您看到修复程序，您可能需要移到V1.11。否则，您将需要编写一个修复程序或围绕自己工作。它们不会修复V1.XX版本。他们死了，你可能被迫搬到2.xx



      以下为原文

    Compare the USB code to Harmony V1.11  See if you can spot any changes.
You may need to move up to V1.11 if you see fixes.  Otherwise you would need to code a fix or work around yourself.
They are not going to fix V1.XX versions.  They are dead.
You maybe forced to move to 2.XX

1.11在哪里？我的MPLAB X IDE V3.30只显示下一个可用的和声是1.0.10。我们在这个项目上不会达到2.03B。我们正在做一些小的更新。下一个项目是使用2.03b。



      以下为原文

    Where is 1.11?  My MPLAB X IDE v3.30 only shows the next available Harmony is 1.0.10.0.  We are not going to 2.03b on this project.  We are just doing minor updates. 
The next project is using 2.03b.

您可以从主MPLAB和谐页面下载HynalV1.11：HTTP://www. McCHIP.COM/MPLAB/MPLAB-Orthyy，并在底部的下载选项卡下查看。这是V1.XX系列版本中最新的（也是最后一个）。



      以下为原文

    You can download Harmony v1.11 from the main MPLAB Harmony page: http://www.microchip.com/mplab/mplab-harmony and look under the download tab on the bottom.
 
This is the latest (and last) of the v1.xx series of releases.

修正是在1.11谢谢



      以下为原文

    The fix is in 1.11. 
Thanks

确保和声版本符合MHC版本。

    Make sure the harmony version matches the MHC version.

FF.C.F.OpenDIR中需要另一个修复。在我们的例子中，SysffsMax文件是1，并且尝试在无效的文件之后访问另一个有效目录，不使用Uness来允许访问另一个目录。FIX是IN fxOpenDR（UntPrTrt句柄，/*指针到目录对象以创建*/const TCHAR *路径/*指针到目录路径*/）{FESREST；FATFS *FS；DuffyNAME.BUF；UTIN 32×HFATFS；dir*dj；（HFATFS＝0；HFATFS & lt；SysffsMax文件；HFATFS++）{if（FATFSDIROPATIOS[HFATFS]）E=＝0）{FATFSDIROBASTH[HFATFS]，iUn= 1；Dj= & FATFSDIROBIDES[HFATFS]。DIROBJ；*（UUTPtRt**）句柄=（UntPrTrtt）和FATFSDIROBIDESP[HFATFS]；中断；}如果（HFATFS & Gt；= SysffsMax文件）{Fr.ValueDIO对象；}如果（！）DJ）FrSUnjistIdObjor；RES＝CHKYLAMP（ANP；PATH，D＆-GT；FS，0）；FS＝DJ-＆FS；IF（RES＝FRSK OK）{InITYBUF（*DJ）；RES＝跟随路径（DJ，PATH）；/*遵循目录*/FREILUBUFE（）的路径；如果（RES＝FRSK OK）{/*遵循完成的*/IF（DJ-＆G.DIR）{/*，它不是根DR*/{ Dir[DriAtthi]和Am didir）{/*对象是一个目录*/dj&＝LDlClSub（fs，dj & gt；dir）；} {对象不是目录*/RES＝Fr.NosiPATH；}（Res＝FrSok）{DJ-& Gt；ID＝FS & Gt；ID；RES＝DrysSDI（DJ，0）；/*ReNoDI**/}}（Res＝Frx NoIX文件）RES＝FR如果（DJ-GT；γ诺维路径；如果函数FAIL**/}否则{DJ-＆GT；FS＝0；}（HFATFS & lt；SysffsMax文件和AMS；RES！）：DJ-& Gt＝FS＝0；/*使DIR对象无效；{FATSOK）{FATFSdiDROPICAT[HFATFS]，UnIs= 0；}/*FieldIf（）*/LaveEfff（FS，RES）；}



      以下为原文

    Another fix is needed in f_opendir in ff.c.  In our case SYS_FS_MAX_FILES is 1 and you try to access another valid directory after the invalid one, inUse isn't cleared out to allow this accessing another directory. Fix is in Bold.
int f_opendir (
uintptr_t handle, /* Pointer to directory object to create */
const TCHAR *path /* Pointer to the directory path */
)
{
FRESULT res;
FATFS *fs;
DEF_NAMEBUF;
uint32_t hFATfs;
DIR *dj;
for(hFATfs = 0; hFATfs < SYS_FS_MAX_FILES; hFATfs++)
{
if(FATFSDirObject[hFATfs].inUse == 0)
{
FATFSDirObject[hFATfs].inUse = 1;
dj = &FATFSDirObject[hFATfs].dirObj;
*(uintptr_t *)handle = (uintptr_t)&FATFSDirObject[hFATfs];
break;
}
}
if(hFATfs >= SYS_FS_MAX_FILES)
{
return FR_INVALID_OBJECT;
}
if (!dj) return FR_INVALID_OBJECT;
res = chk_mounted(&path, &dj->fs, 0);
fs = dj->fs;
if (res == FR_OK) {
INIT_BUF(*dj);
res = follow_path(dj, path); /* Follow the path to the directory */
FREE_BUF();
if (res == FR_OK) { /* Follow completed */
if (dj->dir) { /* It is not the root dir */
if (dj->dir[DIR_Attr] & AM_DIR) { /* The object is a directory */
dj->sclust = ld_clust(fs, dj->dir);
} else { /* The object is not a directory */
res = FR_NO_PATH;
}
}
if (res == FR_OK) {
dj->id = fs->id;
res = dir_sdi(dj, 0); /* Rewind dir */
}
}
if (res == FR_NO_FILE) res = FR_NO_PATH;
if (res != FR_OK) dj->fs = 0; /* Invalidate the dir object if function faild */
} else {
dj->fs = 0;
}
if (hFATfs < SYS_FS_MAX_FILES  && res != FR_OK )
{
FATFSDirObject[hFATfs].inUse = 0;
} /* end if() */
LEAVE_FF(fs, res);
}

我需要更新我对FXOPEN所做的更改。我希望这些变化能进入下一个和谐版本。我不需要检查HFATFS是否是SysffsMax文件，在另一个代码执行之前有一个检查和退出。{HFATFS.Max文件；HFATFS+++）{if（FATFSDIROPATION[HFATFS]，iUn=＝0）{FATFSDIROBASTION[HFATFS]，UnIs= 1；DJ=和FATFSDIROBIdStudi[HFATFS]。DIROBJ；*（UntPrTrt**）句柄=（UntPrTrtt）和FATFSDIROBIdPAS[HFATFS]；中断；} if（HFATFS & Gt；= SysffsMax文件）{ HFATFS；DR*DJ；（HFATFS＝0）返回Fr.ValueDIO对象；}如果（！）dj）{FATFSDIROPATION[HFATFS]，UnSuff= 0；返回RIS= CHKYLAMP（AND；PATH，D＆-GT；FS，0）；FS＝DJ-＆G.FS；IF（RES＝FRSK OK）{InITYBUF（*DJ）；RES＝跟随路径（DJ，PATH）；/*遵循目录*/FREFIUBUFE（）的路径；如果（RES＝FRSK OK）{/*遵循完成的*/IF（DJ-&）/*它不是根dir*/f（dj-gt；dir[DriAtthi] and Am didir）{/*对象是目录*/dj-gt；sClase= LDlClSub（fs，dj-gt；dir）；} {对象不是目录*/RES＝Fr.NoYePATH；}（Res＝FRSK OK）{DJ-GT；ID＝FS & Gt；ID；RES＝DrysSDI（DJ，0）；/*ReDeDIR Dr）{*/}}（RES＝FRS- NONIX文件）RES＝FrSoNoYePATH；IF（RES）！如果函数FAIL**/}否则{DJ-＆GT；FS＝0；}（RES），DJ & Gt；fs＝0；/*使DIR对象无效；{FATSOK）{FATFSdiDROPICAT[HFATFS]，UnIs= 0；}/*FieldIf（）*/LaveEfff（FS，RES）；}



      以下为原文

    I need to update the changes I made to f_open.  I hope these changes get put into the next Harmony version. I didn't need to check if hFATfs is < SYS_FS_MAX_FILES, there is a check and exits before the other code is executed.
 
int f_opendir (
uintptr_t handle, /* Pointer to directory object to create */
const TCHAR *path /* Pointer to the directory path */
)
{
FRESULT res;
FATFS *fs;
DEF_NAMEBUF;
uint32_t hFATfs;
DIR *dj;
for(hFATfs = 0; hFATfs < SYS_FS_MAX_FILES; hFATfs++)
{
if(FATFSDirObject[hFATfs].inUse == 0)
{
FATFSDirObject[hFATfs].inUse = 1;
dj = &FATFSDirObject[hFATfs].dirObj;
*(uintptr_t *)handle = (uintptr_t)&FATFSDirObject[hFATfs];
break;
}
}
if(hFATfs >= SYS_FS_MAX_FILES)
{
return FR_INVALID_OBJECT;
}
if (!dj ) {
FATFSDirObject[hFATfs].inUse = 0;
return FR_INVALID_OBJECT;
}
res = chk_mounted(&path, &dj->fs, 0);
fs = dj->fs;
if (res == FR_OK) {
INIT_BUF(*dj);
res = follow_path(dj, path); /* Follow the path to the directory */
FREE_BUF();

if (dj->dir) { /* It is not the root dir */
