MDK version 5.01 and earlier
SYMPTOM
When the pack installer of MDK 5.00 performs a 'Check for Updates', you may see the error message:
Reading one or more Pack descriptions failed
The error window may look like this:
CAUSE
On February 21, 2014 some new Device Family Pack (DFP) files have been published in a even newer file-format. The change from format specification V1.1 to V1.2 was necessary to fully support new devices. The error shows up because ?Vision version 5.00 (and later) and its ack Installer are not designed to work with version 1.2 files.
On December 19th 2013, some new Device Family Pack (DFP) files have been published in a new file-format. The change from format specification V1.0 to V1.1 was necessary to fully support new devices. The error shows up because ?Vision version 5.00 and its ack Installer are not designed to work with version 1.1 DFP files.
RESOLUTION
The error window can be closed and existing projects can be continued. However, no new Device Family Packs can be installed with MDK 5.00 only packs with the 1.0 schema will work. Please update to MDK version 5.10 or newer. You may download the latest updates from the Keil Website.
If an update is not possible for any reason, you can close this error window and the ack Installer will continue to work without those new device family packs listed in the error dialog. Your ?Vision project will also continue to work as expected.
Please note that it is possible to install a new DFP manually on MDK 5.0 but ?Vision will not be able to use the new devices. DFPs can be downloaded from http://www.keil.com/dd2/pack/ and can then be imported and installed with the ack Installer. Whenever ?Vision 5.00 needs to read the device database, the following error messages will show up:
{var%20f='http://v.t.sina.com.cn/share/share.php?appkey=1515056452',u=z||d.location,p=['&url=',e(u),'&title=',e(t||d.title),'&source=',e(r),'&sourceUrl=',e(l),'&content=',c||'gb2312','&pic=',e(p||'')].join('');function%20a(){if(!window.open([f,p].join(''),'mb',['toolbar=0,status=0,resizable=1,width=440,height=430,left=',(s.width-440)/2,',top=',(s.height-430)/2].join('')))u.href=[f,p].join('');};if(/Firefox/.test(navigator.userAgent))setTimeout(a,0);else%20a();})(screen,document,encodeURIComponent,'','','https://www.xiaopingtou.cn/data/attach/logo/logo.png', '推荐 flyheart 的问题《MDK5.10 的问题，弹出reading one or more pack descriptions failed》','https://www.xiaopingtou.net/q-131591.html','页面编码gb2312|utf-8默认gb2312'));){kind=link}
我在MDK官网似乎找到了相应解释，但是他说5.10之前才会，但原子给的是5.10
