Cannot progam to EIM'S NOR flash with Segger's J-Link + J-FLasher ( Item verification error )

[tamotsu]

Hello.

I use Spansion's S29GL256S NOR flash for EIM.

I set up EIM with the MCIMX7D reference manual to page 20280.

I also set the DATA-BUS pins IOMUX_SW_MUX_CTL_PAD_LCD_DATA00 to _DATA15 to EIM.

I checked the timing of CS0 and address operation using an osilloscope.

However, an Item verification error appears.

Arethere any other items to configure?

Hello, I hope you are doing well.

Do you want to flash the image through Segger's J-Link + J-Flasher?

For that I have understood it is not be possible to do this, please note that JTAG in the i.MX devices, excluding the RT family, is used for the debug purpose only. To download to a flash memory, you may use UUU tool.

Best regards.

Hello.

I didn't understand that the JTAG port on the MCIMX7D was only for debugging.

I'm going to stady the UUU tool you taught me.

Thank you.

Hello JorgeCastañeda.

I understand that UUU is required. Plese tell me about JTAG.

Wven ifis not possible to program parallel NOR flash, is it possible to write to OCRAM?

Best regards.
