How do I enable the SRAM1 clock just after Reset on LPC546xx

[danielgull]

Hi,

The reset value after boot of the SRAM1 bit in AHBCLKTRL0 in LPC546xx according to UM10912 is 0. This means the clock to the SRAM1 is disabled after reset. I however need this clock signal to be enabled in the startup sequence. How can I enable this bit using assembler code in the startup file? Are there examples out there that already do this that I can just copy?

Many thanks

Dani

Hi,

This bit is set after reset.

I have tested the LPC54608 board with our SDK code, after reset, the AHBCLKCTRL0 is really 0X18B, 
I also attach my debug test result, you can find both IAR and MDK project, after reset, the AHBCLKCTRL0 is 0X18B, 

I reported this issue.
