Limitation of writing the Image by MFG tool.

[keitanagashima]

Hi, Sir or Madam,

Is there limitation on compatible device in the writing to Flash memory in by MFG tool?

I'd like to use the Spansion (S25FL132KOXMFI010) [256KB x 8bit].

OS: Yocto L3.10.31.

Best Regards,

Keita

Hi Keita

MGG Tool uses kobs-ng tool for writing to NAND, kobs-ng looks

for NAND parameters in ..drivers/mtd/nand/nand_ids.c, example

such file can be found below

sunxi-nfc-mtd/nand_id.c at master · yuq/sunxi-nfc-mtd · GitHub

if necessary, new nand entry can be added to nand_ids.c and yocto image

fsl-image-mfgtool-initramfs with new MFG tool firmware, can be rebuilt with new nand supported.

Best regards

igor

Dear Igor,

Hello.

Thank you for your reply.

>for new spi-nor one also needs to rebuild MFG Tools firmware

What is meaning of "rebuild the MFG Tools formware"?

I referred the Chapter 5 in porting guide.

But, I couldn't understand it why does it have an influence on MFG tools?

Hi Keita

MFG Tools firmware is small linux image, so it

makes influence on it too.
