Using SDK Version: 2.9.1 for LPC55S69 and Running lpcxpresso55s69_flashiap1 example, I tried to set system clk to the maximum: 150MHz.
However it generates hard fault once FLASH_Init function is reached (hard fault type showed in image attached).
In base of lpcxpresso55s69_flashiap1 example in SDK Version: 2.9.1
Is there some restriction using iap flash at 150MHz?
Additional setting is required to make it work?
Thanks
Thanks Alice,
I attached flash example project which I am taking as base, coming from SDK Version: 2.9.1 for LPC55S69.
There I am trying to set system clk to 150MHz but it triggers a hardfault. I tried with 100MHz and it works. I would like to know if there are some flash limitation or additional setting required in the case of 150MHz.
Thanks
Hello cgarcia,
From UM we can see
"Flash operations (erase, blank check, program) and reading a single word can only be
performed for CPU frequencies of up to 100 MHz. These operations cannot be performed
for frequencies above 100 MHz. "
