STM32H5 external loader

[AMend.7]

Hi,

 I need the project used to generate the external loader: MX25LM51245G_STM32H573I-DK.stldr. My custom board uses a STM32H563VIT6 and the same octo-spi flash from Macronix used in the STM32H573I-DK board. But with different gpios connections. So this project would be of great help to develop the external flash loader for my board.

Hi all,

Thank you so much, very helpful!

@Tesla DeLorean  i'm using the following pins:

• OCTOSPI1_IO3 --> PF6
• OCTOSPI1_IO2 --> PF7
• OCTOSPI1_IO0 --> PF8
• OCTOSPI1_IO1 --> PF9
• OCTOSPI1_CLK --> PF10
• OCTOSPI1_NCS --> PE11

@ABasi.2Can you share also your configuration for the CSP_QSPI_EnableMemoryMappedMode and CSP_QSPI_WriteMemory fuctions?

Thanks again.

hello Berto

just to give you my setup:

i'm using the following pin with a STM32H563ZIT (on a NUCLEO-H563ZI)

• OCTOSPI1_IO3 --> PD13
• OCTOSPI1_IO2 --> PE2
• OCTOSPI1_IO0 --> PD11
• OCTOSPI1_IO1 --> PD12
• OCTOSPI1_CLK --> PB2
• OCTOSPI1_NCS --> PG6

Hi @ABasi.2 ,

thanks, my configuration is similar as yours, it returns an error in the last check:

for(var = 0; var < SECTORS_COUNT; var++)
{
if(memcmp(buffer_test,(uint8_t*) (0x90000000 + var * MEMORY_SECTOR_SIZE),MEMORY_SECTOR_SIZE) != HAL_OK)
{
while(1); //breakpoint - error detected - otherwise QSPI works properly
}
}

Seems is not writing correctly data on the address 0x90000000

Hi berto

i think there are some dummy clocks in your configuration that are wrong, another guy in this forum have an issue similar to yours and resolve managing the dummy clocks 

check the parameter 

sCommand.DummyCycles

 according to your memory datasheet

[Berto]

Hi @ABasi.2 ,

Thank you! I try to check this parameter, do i need to modify this just in the write funcion or in all commands functions?

The Memory Mapped Mode just uses the same read command template as you can check in command mode.

You should be able to read in 1-bit and 2-bit modes to confirm actual content in the memory so you can determine "written wrong" vs "reading wrong"

[Berto]

Hi,

thanks so much for your suggestions, i'm trying to set up the correct dummycycles parameter.

Just a question, which is your clock configuration to peripheral and octospi prescaler?

[ABasi.2]

hello Berto!

here my ioc file, i'm using the nucleo-H563ZI

hope this helps

notice i have HCLK 250Mhz and the OctoSpi is feeded by the HCLK
