Hello,

We were surprised to find that there is no cypress support for nor flash S29GL256S90GHI010 in IAR ? Is that correct ?

How do we add support for it ? We must use it in a big project.

Thank you,

ran

Hello Ran,

Please contact IAR Technical Support in order to create the support request for the S29GL256S90GHI010

(G = Fortified Ball-Grid Array Package (VBU056) 9 mm x 7 mm package) :

IAR Technical Support 

Hope This helps...

Thank you and regards,

Hi,

I already asked their support,

But they say we should do it ourselves.

That makes using this chip with our products a bit problematic.

This is their response:

"

++++++

IAR Embedded Workbench for Arm supports two STM32H7-EVAL boards:

STM32H753I-EVAL

STM32H743I-EVAL

The flash loaders for those boards can be found in <EWARM>\config\flashloader\ST:

* FlashSTM32H753xI.board

* FlashSTM32H750xB.board

* FlashSTM32H7xx_STM32H750-EVAL.board

* FlashSTM32H7xx_STM32H743I-EVAL.board

* FlashSTM32H7xx_NOR_STM32H750-EVAL.flash

* FlashSTM32H7xx_NOR_STM32H743I-EVAL.flash

Both EVAL boards uses the same flash loader for the NOR part:

* FlashSTM32H7xx_NOR.out

The EVAL boards seem to use a Micron PC28F128M29EWLA NOR memory, according to:

https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-too...

https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-too...

The above flash loader only supports the NOR memory found on the STM32H7-EVAL boards (PC28F128M29EWLA).

It does not support Cypress S29GL256S90GHI010.

To add support for Cypress S29GL256S90GHI010, it should be possible to modify the existing FlashSTM32H7xx_NOR flash loader.

The complete project and source code can be found here:

* Project: <EWARM 8.32.1>\arm\src\flashloader\ST\FlashSTM32x7xx_NOR

* Configuration: FlashSTM32H7xx_NOR

Cypress can most likely provide source code templates that support their NOR flash.

++++

Good luck with your project!

Thanks anyway,

Ran
