Hi, I am using NuttX v9.0.0.
As I see in file stm32_rcc.c the IO compensation cell is enabled before the SYSCFG peripheral is enabled. First there is a call to stm32_iocompensation(), and then to rcc_enableperipherals(). Thus the code tries to access registers to SYSCFG, before clocking is enabled to this system. I went ahead and enabled CONFIG_STM32_SYSCFG_IOCOMPENSATION. Indeed the code hangs in the loop in stm32_gpio.c line 816 while waiting for the IO cell to be enabled. I believe this is a bug. Or I am missing something? I would expect to first enable all clocks, and then set-up the IO cell.
