XU216-512-TQ128 QFlash xflash problem Topic is solved

[zhengyang0512]

I have customized a board using the XU216-512-TQ128. The reference design is the Multichannel Audio Board,which uses the XE216-512-TQ128. The QSPI memory type is the IS25LQ080B.
First, using the xtag run as the program, everything works well.
Next, I flash the binary, but the xtimecomposer create the wrong orders:please verify that sqi flash is supported and that correct sqi ports are defined within your xn files

I have read the 《xTIMEcomposer-User-Guide》, IS25LQ080B is in the

30 List of devices natively supported by libquadflash

So I guess the SQI type is good.

My code is simple

Code: Select all

#include <stdio.h>
#include <xs1.h>
#include <platform.h>
port test_led = on tile[0]: {XS1_PORT_1A};

void led_test()
{
    while(1)
    {
        printf("this is a good test\n");
        test_led <: 0;
        delay_milliseconds(1000);
        test_led <: 1;
        delay_milliseconds(1000);
    }
}

int main()
{
    par
    {
        on tile[0]: led_test();
    }
    return 0;
}

And this is my .xn file

Reading the XU216-512-TQ128 datasheet

8.1 Boot from QSPI master

it says that the pins used for QSPI boot are hardcoded in the boot ROM and cannot be changed.And my design also obey the rules.

By using the cmd tools, "xflash --verbose myprogram.xe", the output is

If anyone knows the problem, please help, than you very much.

[zhengyang0512]

Yeah, I have solved the problem. The reason is the SQI type, because we choose the same type SQI , but their manufactures are different. And I move the SQI flash on the Multichannel board to the customized board, and the flash works well.

Are you saying that you used a IS25LQ080B not produced by ISSI?

Yes，although their types are both IS25LQ080B , they have different sizes.
