Due to a bug in BSP V4.4, updates of the Config Block or updates of the complete flash using the Update Tool will overwrite the MAC Address (serial number) and hardware version with the information stored in the .bin file used for the update. This only applies to Colibri PXA3xx modules. Customers using other operating systems than Windows CE 5/6 or are using PXA 270, Vybrid, Tegra, or i.MX 7 modules are not affected!
Note: This problem doesn't affect most customers. It could only lead to problems if two affected devices are used in the same Ethernet network or for some specific module hardware/software combinations. See Implication for details.
All Colibri PXA3xx modules running V4.4 BSP are affected.

To improve durability of the data stored in the config block area of Colibri PXA3xx modules we introduced ECC error correction for this flash area in V4.4 of the BSP. This change lead to a problem when accessing the config block from the kernel under some circumstances. Such circumstances apply when using the Update Tool to update the config block of a module. This happens for example if you make use of the "cloning" on a module in your production programming process. If your update process overwrites the config block, the MAC address (same as serial number) and the hardware version will be overwritten with the settings from the original module you used to create the clone master copy .bin file. Normally this gets adjusted back to the right settings for each module during the update process executed by the Update Tool. A bug in the kernel prevented this from happening which leads to losing the correct MAC address and hardware version.
We've been using BSP V4.4 as pre-installed image on our computer on modules. Therefore you might be affected by this problem even if you don't use the V4.4 BSP by yourself. We started using BSP V4.4 as pre-installed image on April 24th, 2015. Modules you received prior to that date won't be affected by the problem. The affected modules are mainly within the following serial number ranges:
|Modules with V4.4 BSP pre-installed|
|00043922 - 00045422|
|02683983 - 02687797|
|02714634 - 02714729|
|02718504 - 02733071|
Having modules with the same MAC address could lead to problems when used in the same Ethernet network. This might not be a problem for most customers as their devices aren't operating in the same Ethernet network.
Having modules with the wrong hardware version will lead to non functional Ethernet driver for the following combinations:
|Product Number||Product Name||Programmed HW Version|
|00031xxx||Colibri PXA320 806MHz V1.x||V2.x|
|00032xxx||Colibri PXA320 806MHz V2.x||V1.x|
|00061xxx||Colibri PXA320IT 806MHz V1.x||V2.x|
|00062xxx||Colibri PXA320IT 806MHz V2.x||V1.x|
A new Update Tool V5.11.0 is available for download. Using this Update Tool prevents overwriting the MAC address and hardware version on V4.4 BSPs. Just use this tool in your production programming process instead of the pre-installed one in the V4.4 image or any other older update tool.
You can use the new Update Tool V5.11.0 to create a clone (backup.bin) file. The new update tool patches the config block section in a way which allows you to use older update tools in combination with BSP V4.4 without overwriting the MAC address and hardware version. This solution might be interesting for you, if you cannot or don't want to change the update tool which is used to do the update on a V4.4 BSP. This is also the case if you are using the UpdateLib to create your own update tool. Using the .bin file created by the new Update Tool V5.11.0 would allow you to continue using your current update process.
We just released a BSP and image V4.5 for PXA modules which fixes the problem in the kernel and includes the new Update Tool V5.11.0. Upgrading to V4.5 is only recommended if you use BSP or image V4.4 on a Colibri PXA3xx module in your product. Using V4.5 would prevent problems when updating V4.4 based products in the future. You can download the BSP and image V4.5 from our download page. Information about the changes can be found on the release notes page.
In case you have modules with a wrong MAC address or hardware version and you would like to set it correctly, you can restore the information manually by using the Bootloader command prompt mode or the Config Block Editor tool:
Command example when using the bootloader command prompt:
When in Bootloader menu: x (to enter the command prompt mode) set mac.cid=00000000 (use 8-digit serial number found on the barcode label of the module) save mac set hw.vermaj=2 set hw.vermin=0 set hw.variant=1 (0=A, 1=B, 2=C, etc.) save hw (this saves the HW version to V2.0B. You can find the HW version on the barcode label of your module)
Note, restoring it to the right values is only necessary if you are affected by the implications mentioned above.
