Viewing the FT90X peripheral registers in the Eclipse debugger
« on: February 03, 2022, 05:19:00 PM »

Hi,

I've just started evaluating the FT900 MCU but am unfamiliar with the Eclipse toolchain. I'd like to be able to examine the peripheral register contents while debugging, but when I try and view the memory area containing the registers (base address = 0x10000) I just see 0xFFFF and the contents cannot be modified either, whereas I can examine and modify the RAM areas fine. Is it possible to view the peripheral register contents somehow?

Any suggestions would be greatly appreciated!

Problem solved! The base address for the registers is above the 256K shadow program RAM and the 64K data RAM, i.e. at 0x810000. A memory map diagram in the documentation would have made it obvious to a newbie like myself...

Hi,

We are looking into adding a register viewer but in the meantime one other way to view a register is to add it to the expression window in Eclipse. For example, to view a timer peripheral register, you can add this to the expression window.
*((unsigned char *)0x10340)
