&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I am trying to flash code onto the STM32F303 microcontroller on Keil uVision5 MDK-ARM v5.31 using the ULINK2 JTAG debugger. I have the latest packs for the STM32xx_DFP (v2.1.0). Now, whenever I try entering Debug Mode on Keil, I get a &amp;quot;ULINK2/ME - Cortex-M Error&amp;quot; popup message saying: &amp;quot;PDSC: Sequence Execution failed&amp;quot;.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Below is the description in the &amp;#39;Build Output&amp;#39; section:&lt;/p&gt;
&lt;p&gt;------------------------------------------------------------------------------------------------------------------------------&lt;/p&gt;
&lt;p&gt;Cannot access Memory (@ 0xe00fffe4, Read, Acc Size: 4 Byte)&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;Cannot access Memory (@ 0x00000000, Write, Acc Size: 4 Byte)&lt;/p&gt;
&lt;p&gt;Error: Flash Download failed - Target DLL has been cancelled&lt;/p&gt;
&lt;p&gt;&lt;span&gt;------------------------------------------------------------------------------------------------------------------------------&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;My Keil uVision software works fine with the STM32F303 series until a week ago. I am certain my JTAG debugger is not the issue because I am able to run Debug Mode using the JTAG debugger on a custom PCB with an STM32F410 chip. I also do not have issues when uploading code to the STM32F303RE Nucleo board through ST-Link (so I don&amp;#39;t think the issue is with the STM32F3xx_DFP pack). Furthermore, this issue also occurs on the STM32F303C8 and STM32F303K8 when connected through the ULINK2 JTAG debugger.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I have tried deleting the dbgconf file as suggested in this page:&amp;nbsp;&lt;a href="http://www.keil.com/support/docs/4057.htm"&gt;http://www.keil.com/support/docs/4057.htm&lt;/a&gt;. I also tried fully uninstalling Keil uVision5 from my laptop (running Windows 10 64-bit) and deleting the registries in Registry Editor along with Keil folders/files under &amp;lt;users&amp;gt;/AppData/Local/Arm and C:/Keil_v5, and reinstalling everything and the error still persists.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Are there any workarounds to this error? Why did the error appear even though Keil was behaving normally previously? Any help would be greatly appreciated.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Thank you!&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Can&amp;#39;t debug a project</title><link>https://community.arm.com/developer/tools-software/tools/f/keil-forum/44829/can-t-debug-a-project</link><pubDate>Thu, 12 Dec 2019 07:35:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:20390ead-df8e-4c53-9f83-be7b9adf5b98</guid><dc:creator>Aikuka</dc:creator><description>&lt;p&gt;Hello&lt;/p&gt;
&lt;p&gt;I&amp;rsquo;ve been using my STM32L053 DISCOVERY board for a few months. It worked until yesterday. I wrote a program to write a 4 char array to eeprom, under my lecturers supervision, and suddenly my and four of my student mates boards &amp;ldquo;crashed&amp;ldquo; during debugging session. I am using KeilV5.28.0.0 version, toolchain is MDK-ARM Cortex-M0/M0+ 256K.&lt;/p&gt;
&lt;p&gt;Those are the errors that we are getting:&lt;br /&gt;E310 &amp;nbsp;: Debug access failed - cannot read address 0xF0000FE4 (accsize &amp;lsquo;4&amp;rsquo;, AP &amp;lsquo;0&amp;rsquo;)&lt;br /&gt;Error: Flash download failed - Target DLL has been cancelled&lt;/p&gt;
&lt;p&gt;We tried reinstalling the drivers and restarting our computers. We also tried reflashing firmware with STM32CubePrg, changed debug connecting settings in project options - neither of the above works to solve our problem.&lt;/p&gt;
&lt;p&gt;Anyone has any ideas how to solve this?&lt;/p&gt;
&lt;p&gt;Adding a picture of the errors I am getting:&lt;/p&gt;
