Typo in the AM335x(Fast External boot) TRM?

Hello,

Regrding the Fast External Booting, the AM335x TRM pg4549 mentions
Fast External boot "Consists of a blind jump in ARM mode to address 0x00000000 in an external XIP device connected to
CS0"
But the "Figure 26-7" says "Jump to address 0x08000000 in ARM mode".

I believe 0x08000000 is the right address.
Could anybody please confirm this.

Regards.

    Hello Kika

    Section 26.1.7.2 says "Device connected to CS0 mapped to address 0x8000000h" for XIP booting.

    As far as I understand from a program and CPU point of view the start address is 0x8000000, as you say.

    The phrase "address 0x00000000 in an external XIP device" section 26.1.6.1 perhaps refers to the fact that from the perspective of the device within the block accessed when CS0 is asserted (as dictated by the address supplied to it on the bus) this will be address 0x00000000 when CS0 is asserted. From the CPU point of view it will be 0x8000000h. This is perhaps confusing.

    Regards Roger.
