BAM problem: RAppID boot loader error (MPC 5644a)

aperico — Thu, 13 Aug 2015 09:44:52 GMT

Hi,

I am having problems to flash over CAN using BAM.

Below is the error message I get from the RAppID gui:

Error message

"Loss Communication with BAM at Password. Check that Password is correct."

"Password Verification failure"

"Initialization
Error with BAM. Check Password or Verify Boot Configuration Setting
ABS2=1, ABS0=0, FAB=1, Please cycle power and try again."

Our code works normally when flashed over a "universal programmer" (debugging), but we need to be able to flash over CAN (CANCase XL).

* We have FlexCAN0 and FlexCAN1 activated.

I have tried the suggestions from the posts below, but so far, no success:

RAppID boot loader error

Rappid error - cannot boot from CAN with autobaud

Boot Assist Module (BAM) with FlexCAN MPC5604P

From what I understood, I just have to add the following in my code (to enable BAM), is this really all I need to do ?

I cannot understand more than that from the documentation.

-----------------------------------

#define RSTCFG_PCR 210

#define BOOTCFG0_PCR 211

#define BOOTCFG1_PCR 212

...

main(void) {

// BAM -------------------------------

PCR[BOOTCFG0_PCR].B.PA = 1;

PCR[BOOTCFG1_PCR].B.PA = 1;

PCR[BOOTCFG0_PCR].B.IBE = 0; // ABS0

PCR[BOOTCFG1_PCR].B.IBE = 1; // ABS2

RSR.B.BOOTCFG = 0x01;

PCR[RSTCFG_PCR].B.PA = 1;

PCR[RSTCFG_PCR].B.IBE = 0;

... (our normal application code)...

}

Hi,

you can't enable the BAM by software. ABS2, ABS0 and FAB pins or BOOTCFG pins (depends on device) must be configured on hardware level - it is necessary to tie the pins to required voltage level. The state of these pins is read during reset, so they cannot be set by software.

Lukas

Hi ,

I have saw this discussion and I' m intersted about it. A part of the hardware configuration of BOOTCFG pins , Can you only confirm that the RAppID Boot Loader Utility works with the Vector Can Case XL for the MPC5644A? I ask you because before buy that I want to be sure as mauch as possible that there is no bug o problem to use that type of setting for booloading .

Thanks in advance ,

Alessandro.

Hi Alessandro,

yes, Vector CAN Case XL is supported, I'm not aware of issues.

But notice that this tool from Vector is not available anymore. It was replaced by VN1600 devices. I got information from SW team that it's backward compatible and it works too.

Regards,
