Boot from SD in i.MXRT1050

rans — Sat, 27 Oct 2018 18:16:48 GMT

Hello,

I hope someone can help me understand booting from sd as described in :

https://www.nxp.com/docs/en/application-note/AN12107.pdf

I see that the .bd file uses offset 0x0000a0000 in page 28:

"Step 3: Find the linkfile MIMXRT1052xxxxx_ram.icf and change the start vector table from 0x0000A000."

I see in memory map that it is inside ITCM:

0000_0000 0007_FFFF 512KB ITCM

But what is the purpose of offset 0xa000 inside ?

Thank you,

ranran

Hi ranran

" 0xa000" seems as misrpint, one can refer to p.22 attached document.

Best regards
igor
