How to fix the NUCLEO F722ZE Board clock error
I removed the STlink of the NUCLEO F722ZE board and wrote it, but there was a clock error, so the program itself is not working It worked normally when there was Stlink, but it's not working
I set it to HSI and used it, but it didn't work, so a clock issue occurred to switch to HSE, so I thought it would be okay to just debug it, but at some point, the clock didn't work, so it didn't come out of stop mode I set it as an rtc alarm and woke it up, but it seems like a clock error when it stops after going well
How can I fix this error? Stlink uses a lot of electric current, so it needs to be removed
I removed only the stlink from the hardware, but this is the situation
Original settings before removing STlink
Setting changed to clock error after removing STlink
This is the setting I used before, but after removing the STlink, the HAL_RCC_OscConfig(&RCC_OscInitStructure) error handle occurred in this part
