MPC5744P Flash

eautopower — Thu, 13 Jul 2017 07:23:55 GMT

Hi:

How do I implement FLASH read, write, and erase?

I read datasheet. Is the address code downloaded to FLASH 0X01000000-0X01FFFFFF?

if i want to do CAN bootloadr, I wrote the application layer in Simulink,How to change the interrupt vector?

There is an official interface to the Flash API.

I do the CAN boot loader, APP is divided into two projects, APP HEX data written to Flash.

Hi:

Can you give me the read, write and erase FLASH for reference?

Hello,

On our web site there is complete flash SSD driver for MPC5744P.

http://www.nxp.com/downloads/en/device-drivers/C55_JDP_SSD.exe

Documentation is attached to driver.

After reading it you should have no issues to work with flash.

Peter:

i have already see the Documentation,but i still unknow about Flash block select .

like:

the datasheet say middle block number is six:

if i want erase the 0x00FD000-0XFDFFFF block, the MIDSEL[3] =1?

look this program:

why the C55FMC.LOCK0.R = 0X00000200 is unlock mid block 0x00FB_8000 - 0x00FB_FFFF?

datasheet no any information.

Download and extract, there are C55 FLASH manual and demo.

The following is the interrupt vector table sections.ld file.

.intc_vector_table : ALIGN(4096)
{
*(.intc_vector_table)
} > m_text

You can add an interrupt vector table to the code that links to the flash
Const uint32_t __attribute __ ((section (". Intc_vector_table"))) IntcIsrVectorTable [] = {};
You can then operate on the register.

// Initialize the core IVPR
Xcptn_xmpl ();

// Select software (HVEN = 0) or hardware (HVEN = 1) vector mode
INTC_0.BCR.R = 0x00000000;

// Set the INTC ISR vector table base address.
INTC_0.IACKR0.R = (uint32_t) & IntcIsrVectorTable [0];

These files, the new project will automatically generate this code.

Hi kun:

thank you for your reaply.

Can you provide examples of your C code about flash erase and write to me?

For MPC5744P, I'm a beginner,I read the API you gave me, I don't know very well.

thank you very much,

Hi Peter,

About SSD driver, Could you give me a demo project (S32DS, MPC5746R), many thanks.

Re: MPC5744P Flash

petervlna — Mon, 06 Nov 2017 12:56:25 GMT

Hi,

There is no example project in S32DS for MPC5746R.

But the SSD package is driver. So I see no issue here to use it with S32DS.
