Kinetis series NAND Flash Controller (NFC) the CE1 function has some problems

liu_fuchuan — Sun, 07 Jul 2013 13:27:02 GMT

Hello everyone, I am going on a project using MK20FN1M0VLQ12, using NAND Flash Controller (NFC) built in the MCU to control Samsung 2GB of flash, the part number is K9WAG08U1M,and its specific parameters you can refer to the attachments. TThe Samsung 2GB flash contains two 1GB of FLASH,one of them is selected by the pin CE0, CE1 , and its READY/BUSY state feedback is given by the R/B0 or R/B1 pin. The K series MCU have NFC chip select CE0, CE1, and just one READY/BUSY pin (R / B). My design connects the two pins ,R/B0 and R/B1 of the Samsung 2GB flash hardware ,together to the NFC's R / B pin.And the CE0,CE1 are connected to their corresponding NFC pins. Using the Freescale official DEMO, when the NFC chip select CE0 is enable, choosing the first piece 1G of the FLASH, the block erase, page program, page read functions are right, but when the second piece CE1 is enable, the write error occurs. The specific phenomenon is: when either block erase or page write is done , then I read out the value of the corresponding address that has been erased or writen,but the value are weird: dozens of 0x30303030 appears at the begin of the data that read out, then the correct data seems like appear by a left shift. Data is shown in the attachment text. Program is also shown in the attachment.

Ps: my colleague using the K60 chip board encountered the same problem. Initially concluded that the problem should be in the CE chip select and R / B pins, or the Timing aspects. Please help to analyze the problem combining the information given above. I'm confused by this problem for a long time,Please provide some help, thank you!!!

Hi,

For there only with one NFC_RB pin available for both chip select NFC_CE0 and NFC_CE1. Please set both [RB1] and [RB0] at NFC_RAR regiser, when you are using NFC_CE1.

Wish it helps.

Are you sure about that Ma Hui? Because the K20 manual contradicts that advice... from the NFC_RAR field description:

RB1

Determines if NFC_R/ B 1 is waited on a wait for R/ B command. If an equal number of NFC_CE and NFC_R/ B lines are used, the CS n and RB n fields must contain identical values. If only one NFC_R/ B is used, then CS n determines the true chip select, and this field is always 0.

0 NFC_R/ B 1 is disabled
1 NFC_R/ B 1 is enabled

24 Ready/busy 0 enable

RB0

Determines if NFC_R/ B 0 is waited on a wait for R/ B command. If an equal number of NFC_CE and NFC_R/ B lines are used, the CS n and RB n fields must contain identical values. If only one NFC_R/ B is used, then CS n determines the true chip select, and this field is always 1.

0 NFC_R/ B 0 is disabled
1 NFC_R/ B 0 is enabled

I'm working with a K20 and have two separate NAND flash, with R/B connected together, and the second NAND (on CE1) isn't working, I'm getting the '0303' pattern...

Hi Marc,

I got the confirmation mail from Kinetis product team. For your issue, Please set both [RB1] and [RB0] at NFC_RAR register, when you are using NFC_CE1.

Wish it helps.

Best regards,

bowerymarc — Fri, 25 Apr 2014 17:20:50 GMT

when will you issue an errata with this change, as it directly contradicts the reference manual?

Hi Marc,

That will be ok to post a notification at reference manual.

I will forward related info to Kinetis document team.

Thank you for the comments.

best regards,

Hi Ma Hui,

OK some more investigation. With my board setup (K20F120M and two MT29F16G16 NAND flash, with page set to 2113 due to another bug (i.e. 2048 data 64 spare, 60 byte ECC)), I wrote constant incrementing bytes to a page on the NAND at CE1 (after erasing the block) and here is what I got. I'm guessing there is something odd going on with the NFC buffer mapping? I have all mapping set to normal, as I'm dealing with full pages only (btw, once working around the bug regarding the spare area, the NAND at CE0 works perfectly). Here's the dump of the page:

Re: Kinetis series NAND Flash Controller (NFC) the CE1 function has some problems

bowerymarc — Fri, 16 May 2014 23:55:47 GMT

Hi Hui Ma,

Again, I have found that you can NOT use both [RB1] and [RB0] in NFC_RAR when using CE1. I found that if you do that during a block erase, you erase BOTH of your NAND chips at that block.

Regards,

Marc

Hi,

So far, we found a document issue at Kinetis 120MHz NFC module.
