MCIMX233DJM4C A5M88S recovery mode problem

cabarnes — Mon, 02 Feb 2015 16:20:47 GMT

After asserting the PSWITCH pin, the device enumerates into USB HID mode as expected, and shows up as a HID device in the MfgTool (version 1.6.6.004) on Windows XP, but does not switch into USB mass storage mode to receive the firmware update code file. Windows device manager shows an error (yellow mark) on the enumerated HID device. Our older parts (MCIMX233DJM4B A4M88S) work fine with this process.

Is the recovery mode process different between these two parts?

Hi Clif

seems there is no problem in recovery mode, since

in both cases parts enumerate into USB HID mode as expected.

USB mass storage appears when processor successfully runs

firmware (updater.sb, small linux image) in DDR.

USB mass storage mode may not show due to possible

brown-out events or DDR errors (they are configured in

/imx-bootlets-src-xxx/boot_prep/init-mx23.c, power_prep.c).

Bootlets sources may be prepared in ltib (in ltib/RPM/Build):

./ltib -m prep -p boot_stream.spec

rebuild image

./ltib -p boot_stream.spec -f

also recommended to use latest tools from i.MX23 EVK official page

mfgtools-rel-REL_1.6.2.006.1.tar.gz I.MX23_MANUFACTURING_TOOL

IMX_MFG_TOOL : Tool and documentation for downloading OS images to the i.MX53,

i.MX51, i.MX50, i.MX28 and i.MX23.Size (K): 241193 Format: zip Rev #: 1.6.2.048

Note that for revision MCIMX233DJM4C one needs to implement linux patches

in custom software

L2.6.31_10.05.00_SDK_PATCHES : Patches for the Linux 10.05 Release.

Igor,

I have updated the MfgTool to 1.6.2.048 but it then gave me an error saying "Invalid Player Profile."

I changed the player.ini file to say VERSION=2, which made that error go away. However, when I try to run, I get another error "Unrecognized device"

How can I use the profile from the previous MfgTool (version 1.6.2.004) with this version of the MfgTool (version 1.6.2.048)?

Hi Clif

I think you can not use old profile since they can be

uncompatible, just rebuild firmware for new version of MFG Tools

Best regards

Igor,

I have updated the profile that I was using to work with the new version of the MfgTool (1.6.2.048). I am now able to successfully program the older (MCIMX233DJM4B) parts. However, there is still an issue with the newer parts (MCIMX233DJM4C). I have attached to the debug UART and it appears that the updater is never is downloaded and run on the 4C parts.

Here is the output for the 4B parts after hitting start in the MfgTool :

PowerPrep start initialize power...

Battery Voltage = 3.99V

5v source detected.Valid battery voltage detected.Booting from battery voltage source.

(everything stops here)

I'm using the exact same MfgTool, same profile, and same binaries for each.

Why would it fail to download the updater for the 4C parts?

Do any of those messages indicate an error?

Clif

had you tested memory with new chips ?

This may be caused by DDR errors, they are configured in

/imx-bootlets-src-xxx/boot_prep/init-mx23.c.

Igor,

I have compiled in the memory test, but it shows no errors:

PowerPrep start initialize power...

Battery Voltage = 3.63V

It appears that this test only tests by reading and writing 1000 ints to memory. Is there a more exhaustive test available that tests address lines, data lines, and reading/writing all memory?

Hi Clif

I think one can reuse one for i.MX28

Igor,

I downloaded the mem_test.7z.zip that you linked to and attempted to run it. However, I got the following errors on the host:

C:\mem_test>sb_loader.exe /f test.sb

Downloading test.sb to device.

. CStHidDevice::Download() Error(1167) during read.

Quitting.

Error(1167) during download.

Quitting.

The device side just printed:

Data Abort

It appears that this utility was made for the i.MX28 and is not compatible with the i.MX233. Is there a way to modify it to work with the i.MX233?

Clif

one can run memory tests with jtag.

Igor,

Are there recommended serial JTAG debuggers for use with the i.MX233? I found this one: IMX233-SJTAG Olimex LTD | 1188-1085-ND | DigiKey. Would it work?

Do you have any documentation for how to run memory tests using the JTAG?

Yes Clif,

it can be used, also please find attached file.
