i.MX233 NAND

[federicodevitii]

Hi,

i've build a i.Mx233 (128-QFP) based board with a 29F8G08ABABA NAND. I connected  GPMI_CLE, GPMI_ALE, GPMI_CE0# (pulled up via 47k resistor), GPMI_RE#, GPMI_WE#, GPMI_WP# (pulled down via 47k resistor), GPMI_R/B0# (pulled up via 47k resistor) from soc to nand, and on the nand i connected VSS1&VSS2 to gnd and VCC1&VCC2 to 3v3.

When i try write the flash via mfgtools, the nand is not recognized.

whats' wrong?

i wrote via bitburner in the HW_OCOTP_ROM1 register  the bit NUMBER_OF_NAND to1 and ENABLE_NAND0_CE_RDY_PULLUP to blown (it's redundant with the pull-up resistor, i know)

can someone help me, please

Thank you in advance

Hi Federico

one needs to add entries as shows attached file, so linux could recognize NAND.

Then mfg tools firmware should be rebuilt. For baremetal test one can reuse i.MX28 OBDS

GpmiNandReadId()  stmp_nand.c:

Lab and Test Software (1)

On-Board Diagnostic Suit for the i.MX28 (REV 1)

i.MX28 Evaluation Kit|Freescale

Hi igor,

i followed the istruction of User Guide for i.MX28 On-Board Diagnostics Suite (OBDS) for build a mx28-obds.sb file and flashed it on sd, but when boot a message appear on console

Undefined Instruction

r14_un

i tried to usb boot using sb_loader with the same results

after this i edited the build_mx28.sh script to chagne the elftosb option from "-f mx28" to "-f mx23" but at the end of building an error message say:

error: line 20: HAB features not supported with the selected family

thank you

[igorpadykov]

Hi Federico

one can run it with jtag

Hi Igor,

loading other sb file (u-boot, linux kernel etc...) built for imx23 there is no problem with SD or USB. The problem is when i try to start MX28 OBDS on MX23 platform, because i think there is some instruction, like the HAB one, not supported from imx23

regards

Federico
