Hi trying to run the STM32G071 at a low power(1Mhz sys clock), thus don't want/need PLL.
mcuconf.h is this
#define STM32_HSIDIV_VALUE 16
#define STM32_HSI16_ENABLED TRUE
#define STM32_HSE_ENABLED FALSE
#define STM32_LSI_ENABLED TRUE
#define STM32_LSE_ENABLED FALSE
#define STM32_SW STM32_SW_HSISYS
#define STM32_PLLSRC STM32_PLLSRC_NOCLOCK
but getting a load of errors ?

Re: STM32G071 No PLL
Hi,
Moving in bug reports, probably there are some missing conditions in checks.

Re: STM32G071 No PLL
Hi,
As a work around, until the PLL checks are updated, if you set the following you should be able to build from trunk...

Code: Select all

#define STM32_PLLN_VALUE 16
#define STM32_PLLP_VALUE 2
#define STM32_PLLQ_VALUE 4
#define STM32_PLLR_VALUE 4

Re: STM32G071 No PLL
Hi,
The problem is caused by specifying STM32_PLLSRC_NOCLOCK as clock source and then specifying the PLL as clock source for some peripheral, for example in my case STM32_ADCSEL_PLLPCLK, after changing it to STM32_ADCSEL_SYSCLK the error disappeared.
If you disable the PLL make sure no not use it as source for any clock or HAL will try to activate it and find that the input clock is invalid.

Re: STM32G071 No PLL
got another one, trying to output SYSCLK to MCO pin PA8 to check the SYSCLK is at correct Frequency.
So have set this, along with PA8 to Alternate 0
#define STM32_MCOSEL STM32_MCOSEL_SYSCLK
#define STM32_MCOPRE STM32_MCOPRE_DIV1
