LPC1833 external SPI flash bootloader
« on: May 16, 2021, 03:01:12 am »
Hi, there,

   I am not sure if this forum is alive or not, but I have no other way to solve my issue which stucks me more than 2 months cause I am totally a hardware designer, know little about coding, but no one can help me for this.

here my issue is we implement 2 second source external SPI flash IC for LPC1833, so the original bootloader for one time FW updating into flash is nolonger workable for new SPI flash ICs, the situation now is the original bootloader source code has lost, and no one know the next step in my company

now I need help from flash magic,

1. does flash magic have example code for LPC1833 external SPI Flash bootloader?

2. could flash magic support to teach us how to modify the bootloader code for new SPI flash?

3. if flash magic don't support to teach how to modify the bootloader code, is there any reference documents for LPC1833 external SPI flash bootloader?

4. could flash maigc support to teach the steps to set the MCUXpresso IDE v11.3.1_5262 and Keil uVision5 for LPC1833 external SPI flash bootloader code compile?

We include an example for the LPC18S37 that uses SPIFI. See the Bootloaders\External Memory\LPCxpresso18S37 folder in the installation. It may work out of the box for you or it may need modifying.

We can customize and test this for your hardware as part of a consulting project - please contact us for a quote info at esacademy dot com.
