St Link Utility : writing a new external loader

Hello,,

I need to write (or modify) a new External flash loader for StLink utility.

I'm using a STM32F475RCT6 with a N25Q128A13EF840E Quad Spi Flash.

It's seems to be very similar to the example given with StLink Utility (STM32L476G_EVAL\Examples\QSPI\N25Q256A_STM32L476G-EVAL).

For me, the first step is to compile the software given as example.

Compiler : IAR

Version : 7.70.1

After renaming the elf file in stldr and copying it in the directory C:\Program Files\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader\, the external loader is seen by StLink Utility.

But :

- the external loader has no name - the 2 features available are Sector Erase and Program - no sector description is available for sector erase - Erasing, Programming or reading the externam flash is impossible

What are the good conditions (Define, ...) for compiling the project given as example?

Thanks

Hi there!

You were talking about the following folder?:

ExternalLoader\\N25Q256A_STM32L476G-EVAL_Cube\Projects\STM32L476G_EVAL\Examples\QSPI\N25Q256A_STM32L476G-EVAL\

We can't find this folder anywhere. 

For our project we are also searching for this example. Is it possible to send us a zipped file with that template?

Best regards,

C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader\N25Q256A_STM32L476G-EVAL\Sources\Loader_Files\Loader_Src.c

from the v3.9.0 or v4.x.x installs as I recall
