<p><span style="font-weight: bold;">STMCube is an STMicroelectronics original initiative to ease developers life by reducing development efforts, time and cost.</span></p>
<p>STM32Cube covers STM32 portfolio.</p>
<p>STM32Cube Version 1.x includes:</p>
<ul>
<li><p>The STM32CubeMX, a graphical software configuration tool that allows to generate C initialization code using graphical wizards.</p></li>
<li><p>A comprehensive embedded software platform, delivered per series (such as STM32CubeC0 for STM32C0 series)</p>
<ul>
<li><p>The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio</p></li>
<li><p>A consistent set of middleware components such as ThreadX and LevelX]</p></li>
</ul></li>
</ul>
<p>The STM32Cube firmware solution offers a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements.</p>
<p>Both the HAL and LL APIs are production–ready, checked with CodeSonar® static analysis tool, and developed in compliance with MISRA C® guidelines. Reports are available on demand.</p>

<ul>
<li>This patch release does not bring any functional changes, it highlights a limitation fixed in release v1.3.0 but undisclosed in the Release Notes.</li>
<li>Below, you will find detailed information about the limitation, conditions under which this issue occurs, the root cause, and the proposed solution.</li>
</ul>
<h2 id="contents-2">Contents</h2>
<h4 id="description-of-the-limitation"><u>Description of the limitation</u></h4>
<p>Before setting the system clock (SYSCLK) frequency to 48 MHz, the flash memory latency must be set to one wait state.</p>
<p>However, the code generated by STM32CubeMX (versions before v6.13.0), and the project examples available in the STM32CubeC0 software packages (versions before v1.3.0), do not ensure this.</p>
<p>Consequently, the HardFault exception may occur when the following condition is met:</p>
<ol type="1">
<li>The HSI48 clock (HSISYS) is selected as SYSCLK source (default upon reset)</li>
<li>The HSI48 clock division factor is equal to or greater than two, which results in a HSISYS clock frequency equal to or lower than 24 MHz (default upon reset), and</li>
<li>The code generated by STM32CubeMX or based on the software examples provided by ST in STM32CubeC0 increases the HSISYS clock to 48 MHz (by setting the HSI48 clock division factor to one), without previously setting the number of wait states to one. As a result, during a period, the flash memory is clocked at 48 MHz with zero wait states.</li>
</ol>
<p>The failure mechanism is as follows:</p>
<ol type="1">
<li>HSISYS is used as SYSCLK source, with clock frequency equal to or lower than 24 MHz.</li>
<li>The function SystemClock_Config() contained in the STM32CubeC0 examples and in the code generated by STM32CubeMX:
<ol type="a">
<li>calls HAL_RCC_OscConfig() function to modify the HSI48 clock division factor to one, without setting the number of wait states to one, then<br />
</li>
<li>calls HAL_RCC_ClockConfig() function to configure SYSCLK, AHB, and APB buses clocks, and to set the number of wait states to one.</li>
</ol></li>
<li>Between the steps 2a and 2b, the flash memory is clocked at 48 MHz with zero wait states, which may lead to the HardFault exception.</li>
</ol>
<p>The occurrence rate of the HardFault exception may vary from device to device, due to the process variation. It also varies with the temperature.</p>
<h4 id="description-of-the-change"><u>Description of the change</u></h4>
<p>The fix consists in setting the number of wait states to one, before setting the HSI48 clock division factor to one in step 2a. This fix is implemented in the following (and any subsequent) versions:</p>
<ul>
<li>STM32CubeC0 v1.3.0, available at this <a href="https://www.st.com/en/embedded-software/stm32cubec0.html#get-software">link</a></li>
<li>STM32CubeMX v6.13.0, available at this <a href="https://www.st.com/en/development-tools/stm32cubemx.html#get-software">link</a></li>
</ul>
