LPC4370 - issue with custom mounted PCB, programming W25Q80DVSSIG flash chip

[QM]

Hi NXP, 

I have recently designed a custom PCB using a LPC4370 chip which essentially replicates the LPC-link2 schematic except for the flash chip. The W25Q80BVSSIG that was on the LPC-link2 has been made obsolete, so I replaced it with a W25Q80DVSSIG.

However when attempting to upload code onto my board for the first time I got the following error:

This is my first time working with a PCB with a microcontroller and external flash that I have designed myself so I am wondering if there are some steps I need to complete before attempting to upload code such as first using the GUI Flash Tool, or adjusting some settings in MCUXpresso to have the LPC4370 work with this new flash chip. Any advice on how to proceed would be much appreciated, thanks.

Hi Xiangjun, 

I never got the LPC4370 chip working but I now know that the W25Q80DVSSIG flash chip is compatible with the LPC4370, so that is not my issue. 

Is there some specific process I need to follow to boot an LPC4370 for the first time and program flash? I know there are a number of different boot modes available but in my current design I have not connected the USB or UART0 pins. The only pins I have connected to communicate with the chip are the JTAG pins (TMS, TCK, TDO, TDI, NRESET), and UART2 (P2_11, P2_10). Then there is the SPIFI connections to the flash. 

When debugging the same code onto an LPC Link2 via JTAG it works fine.

Note, there could be some issue with my soldering but I am trying to rule obvious things out as it seems to draw the correct current and sit in a standby mode blinking its BOOT0 LED at 1 Hz.

Thanks, 

QM

Hi,

Pls change SPI LPC18_43_SPIFI_GENERIC.cfx to SPI LPC18_43_SPIFI_SFDP.cfx, the two files are located at:

C:\nxp\MCUXpressoIDE_11.9.0_2144\ide\LinkServer\binaries\Flash

You can click the red circle to change the *.cfx file. I only use LPC8xx as a example.

Hope it can help you

Hi XiangJun, 

Thanks for your response. This did not work and I got the same error as above. Anything else I can try? Is there somewhere I can download the correct flash driver for my new flash chip?

Hi,

If the two *.cfx files the MCUXPresso tools integrated can not work because of new spifi flash chip, I suppose that you have to develop the project to generate the *.cfx which adapts to the new spifi flash.

Hope it can help you
