Bootloader CAN nxp5744p

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 ??

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 ?

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.

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?

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