    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Piotr Cerba,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; If you want to check the 0X40D data, you can read the register FTFA_FOPT register in the debugger mode with the IDE after you download the code.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Here I help you to create a KDS project, and modify the FTFA_FOPT to boot from the ROM, take care, the new create project is Booting from the Flash, this will cause you can't connect the blhost.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; The following is the test picture, you will find the FTFA_FOPT is 0XFD, this register is the data from 0X40D,.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="9.jpg"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/58273i9DCC5560D62DC52C/image-size/large?v=v2&amp;amp;px=999" role="button" title="9.jpg" alt="9.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp; Actually, you can just download my code to your chip, then your chip must boot from ROM, and can connect to the blhost.&lt;/P&gt;&lt;P&gt;&amp;nbsp; Please download my code to your chip at first, then reconnect with the blhost again.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Wish it helps you!&lt;/P&gt;&lt;P&gt;If you still have question, please contact with me!&lt;BR /&gt;Have a great day,&lt;BR /&gt;Jingjing&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-----------------------------------------------------------------------------------------------------------------------&lt;BR /&gt;Note: If this post answers your question, please click the Correct Answer button.

      <title>Error - UsbHidPeripheral() cannot open USB HID device while trying to use blhost on KBOOT</title>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I downloaded KBOOT package and uploaded the /apps/binaries/FRDM_KL43Z4.bin to my KL43Z board, while in BOOTLOADER mode.&lt;/P&gt;&lt;P&gt;While trying to ping the board within blhost directory (command: blhost --usb -- get-property 1) I am getting the following error:&lt;/P&gt;&lt;P&gt;"Error: UsbHidPeripheral() cannot open USB HID device (vid=0x15a2, pid=0x0073, sn=)."&lt;/P&gt;&lt;P&gt;The same goes with UART, no COM port is active.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Apparently the bootloader has changed, since it does not show up now as FRDM-KL43Z in My Computer, but somehow it does not work.&lt;/P&gt;&lt;P&gt;What am I doing wrong?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Dear &lt;STRONG style="font-size: 12.6px; font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #51626f;"&gt;Alice_Yang​ &lt;/STRONG&gt;and&lt;STRONG style="font-size: 12.6px; font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #51626f;"&gt; &lt;STRONG style="font-size: 12.6px; font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #51626f;"&gt;Jingjing Zhou​,&lt;/STRONG&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;1. I use KBOOT 1.20 (FSL_Kinetis_Bootloader_1_2_0 folder after extracting the archive)&lt;/P&gt;&lt;P&gt;2. Yes, I have the PEMicro drivers installed, which were working correctly so far, so I assume they are not the problem.&lt;/P&gt;&lt;P&gt;3. Unfortunately I was not following the .pdf file you mentioned. &lt;/P&gt;&lt;P&gt;Now after reading it I can see that:&lt;/P&gt;&lt;BLOCKQUOTE&gt;&lt;P&gt;"To install the bootloader application, drag or copy and paste the appropriate binary (Tower or Freedom) file from&lt;/P&gt;&lt;P&gt;&amp;lt;install_dir&amp;gt;/targets/&amp;lt;device&amp;gt;/binaries"&lt;/P&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;What I did -&amp;gt; I dragged and dropped the FRDM_KL43Z4.bin file from /apps/binaries/ so apparently that was not a proper file?&lt;/P&gt;&lt;P&gt;4. Is there any already prepared .bin (or any other) bootloader file for KL43Z?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG style="font-size: 12.6px; font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #51626f;"&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Piotr Cerba,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; If you want to check the 0X40D data, you can read the register FTFA_FOPT register in the debugger mode with the IDE after you download the code.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Here I help you to create a KDS project, and modify the FTFA_FOPT to boot from the ROM, take care, the new create project is Booting from the Flash, this will cause you can't connect the blhost.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; The following is the test picture, you will find the FTFA_FOPT is 0XFD, this register is the data from 0X40D,.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="9.jpg"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/58273i9DCC5560D62DC52C/image-size/large?v=v2&amp;amp;px=999" role="button" title="9.jpg" alt="9.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp; Actually, you can just download my code to your chip, then your chip must boot from ROM, and can connect to the blhost.&lt;/P&gt;&lt;P&gt;&amp;nbsp; Please download my code to your chip at first, then reconnect with the blhost again.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Wish it helps you!&lt;/P&gt;&lt;P&gt;If you still have question, please contact with me!&lt;BR /&gt;Have a great day,&lt;BR /&gt;Jingjing&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-----------------------------------------------------------------------------------------------------------------------&lt;BR /&gt;Note: If this post answers your question, please click the Correct Answer button.

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thank you Jingjing Zhou, with your project I managed to connect to the board with blhost and program the FRDM_KL43Z4.bin&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Do I have the KBOOT bootloader now present on the board?&lt;/P&gt;&lt;P&gt;I am asking because the device still enumerates as FRDM-KL43Z drive and it seems there is no difference from OpenSDA bootloader. It still has .html file that redirects to PEMicro webpage.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="Capture4.PNG"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/58152iD7871BFBCBF9C05B/image-size/large?v=v2&amp;amp;px=999" role="button" title="Capture4.PNG" alt="Capture4.PNG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;That's very good.&lt;/P&gt;&lt;P&gt;Yes, after you program the FRDM_KL43.bin to your chip, then the code will run your FRDM_KL43.bin code, FRDM_KL43.bin is also from the KL43 driver, so you may see the same phenomena, if you want to see the difference, you can program your own .bin code to it.&lt;/P&gt;&lt;P&gt;&amp;nbsp; You don't need to care about the .html&amp;nbsp; file in Opensda, this is just the debugger, just for the code download and the virtul com.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Wish it helps you!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;Have a great day,&lt;BR /&gt;Jingjing&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-----------------------------------------------------------------------------------------------------------------------&lt;BR /&gt;Note: If this post answers your question, please click the Correct Answer button.

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Is there any way to check the source code of FRDM_KL43.bin ?&lt;/P&gt;&lt;P&gt;In the future if I want to protect my board from eg. debugging do I need to set it somewhere in blhost.exe or do I need to program my own version of FRDM_KL43.bin?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
