MPC567x BAM App

CCandido — Tue, 25 Feb 2020 19:54:03 GMT

Hi,

based in XPC567X, my custom board test BAM CAN App, not run,

loader code length sucess ok, not start App.

pleace you my code resume, see,

Project, CW-5.9, Target-RAM, CPU-5674/5676

LCF: MEMORY{

exception_handlers_p1: org = 0x40002000, len = 0x00001000 //not start
pseudo_rom: org = 0x40003000, len = 0x00005000

CAN_A.MCR.R = 0x0000003F; /* Negate FlexCAN A halt state for 64 MB, AEN=1 */
} //------------------------

convert ram.mot to bin,

send password number ok

send 0x40000000 + (VLE or not)+ Length ok

send 0x13+ data and receiver 03 ok....all file length.

thnkas,

Carlos.

Hi Carlos,

I'm not sure if I can understand the description but have you followed procedure I described here?

Hi Lukas,

yes, I follow the example, but there is a difference, from one core to two core, I imagine.

https://community.nxp.com/thread/320166#comment-384300

my case MPC67x BAM, donloader code ok, not start my App test.

Project, CW-5.9, Target-RAM, CPU-5674/5676,LCF ok.

see difference:

compare maps: with _start.c

questions:

CPU init mode BAM with core0 or core1 ?

simple code init one GPIO to simple led blinks run ?

for bam, the best CORE use, 0/1 ?

thanks,

Carlos.

Hi Carlos,

use core 0. BAM is executed by core 0 and then it jumps to downloaded application, so it is also executed by core 0. Core 1 needs to be started by your application if needed.

CodeWarrior project creates file for both projects, by default. If you use S32 Design Studio, you can select if you want to use one (boot) core only or both cores.

So, always start with core 0 only.

Regards,

Lukas

hi Lukas and others,

i really need help:smileylaugh:

first I tested the cw, then I decided to switch to S32.

BAM-CAN for MPC5674 with CW no run, then I decided to switch to S32 IDE.

I decided to change the processor to MPC5604C, BAM-Serial my App loader code.

S32 led blinks in flash and debug ok

led blinks on Debug RAM code 0x40000100 ok (LCF = RAM)

Bootloader serial all code, not run led blinks.
