iMX287 with S34ML02G200 nand flash memory, kobs-ng error

[sarievruslan]

Hi,

we use a custom board with iMX287 CPU and S34ML02G100 NAND Flash Memory (page 2048+64). Now S34ML02G100 is obsolete and we sold S34ML02G200 NAND Flash chip (page 2048 + 128)  for testing.

In file nand_device_info.c we change geometry 

.page_total_size_in_bytes = 2*SZ_1K + 128,

and rebuild Manufacture Tool updater_ivt.sb

Replace updater_ivt.sb in MFGTool and run it.

But now we get error - 

kobs-ng unsupported geometry (2048/128)

Any ideas?

Thank you, Ruslan.

Hi Ruslan

typical geometry is described in sect.16.2.2 Flash Page Layout i.MX28 Reference Manual

https://www.nxp.com/docs/en/reference-manual/MCIMX28RM.pdf

seems such geometry was not validated, one can try to tweak kobs-ng using sources

GitHub - NXPmicro/imx-kobs: Tool to create and write Freescale/NXP I.MX NAND boot related boot data ... 

Best regards
igor
