Bootloader CAN nxp5744p

[rehab_hassan]

I tried to flash the MPC5744P using CAN and I used a CAN case for that, and I configured both the pins and baud rate as required, but it didn't flash the file and I received the following message.

 
Are there any missing steps to flash the kit successfully using CAN ?
Is it the vector CAN case which is used to flash the kit ??

@stanish any idea for that issue? 

I tried to flash the application using serial and it succeeded but with CAN I still stuck in that issue

any help?

thanks

It flashed using CAN when I changed the following 

flash_rchw : org = 0x00FA0000, len = 0x4
cpu0_reset_vec : org = 0x00FA0004, len = 0x4
delay_us : org = 0x00FA0008, len = 0x4
appkey_addr : org = 0x00FA000C, len = 0x4

But the applications doesn't work 

when I Flashed using serial UART 0 the previous version of the rbf 

the application worked when I write as 

flash_rchw : org = 0x00FC0000, len = 0x4
cpu0_reset_vec : org = 0x00FC0004, len = 0x4
delay_us : org = 0x00FC0008, len = 0x4
appkey_addr : org = 0x00FC000C, len = 0x4

any help with that ?

Or maybe @mikedoidge , do you have an idea what could be wrong if it is not caused by hardware?

@lukaszadrapa any ideas regarding this issue?

could you please attach an application (srec file) to try it just in case if the issue in the application ?

Thank you

[rehab_hassan]

any ideas? 

could you please provide a srec file to try flashing it using the provided rbf? 

I have nxp5744p Rev E 

[rehab_hassan]

Yes I flashed that rbf and I got that error

Hello,

from the attached screenshot it is obvious that the communication has been established.

Seems the Erasing process is being interrupted and causes the communication error.

Could you possibly try to dump some flash memory content ("Read Memory Content" e.g from 0xFC0000 - 0xFC1000).

Is it the only device on CAN bus?  If not can you double check if it does not interfer with other messages with can ID 0?

Hope it helps.

I tried to read and dump Memory

Hi,

I'd suggest to to double check your RESET pin if there is no reset issued during RappID bootloader operation as suggested by Lukas.

Is there any other traffic on CAN bus?

Hi,

I'm sorry for delayed response, I was out of office.

Is there an external watchdog on your board?

Lukas

@lukaszadrapa 

Never mind, 

Yes there is External wdg SBC, 
Development board Dev NXP5744P Rev E 

any certain connection should I do? 

Thank you

[lukaszadrapa]

Is jumper J163 installed? It should be installed to force the SBC to DEBUG mode when it does not trigger watchdog reset.

Regards,

Lukas

[rehab_hassan]

@lukaszadrapa  Yes , Debug mode is enabled

Hi,

see please this HOWTO article:

And you can use this latest version of RBF:
