Customized bootloader for flash ROM Winbond: W25Q16JLSNIG-T with LPC1833

[Anonymous-III]

Hi,

Our requirement is to design a customized bootloader for external flash programming. We have tried the example code of Flash Magic\Bootloaders\External Memory\LPCxpresso18S37.
But, that does not work. Could you guide us on this requirement? Please see our below concerns.

1. do any flash magic versions have an example code for the LPC1833 external SPI Flash bootloader?

2. What are changes needed in Flash Magic\Bootloaders\External Memory\LPCxpresso18S37 that can help us?

3. We have changed the descriptor content in FlashPrg.c file as per the LPC1833 memory map, but that also does not work. We got the error as "Bootloader is not executing in RAM".

4. Please find the attachment and help us to provide some details about the requirement.

Thanks,

Jigar

Hi Edwin,

We are able to flash W25Q16CL with our customized bootloader.

The change was in RAM location to be loaded. We had used code example of "LPC1857-Keil" and modified for LPC1833.

Thanks,

Jigar

Hello @Anonymous-III

I was going to propose contacting the members of the Flash Magic Forum directly (specifically for your first question) but I see that you have already done that. Feel free to keep us updated in case your post on the Flash Magic Forum does not get resolved.

Best regards,

Edwin.
