We evaluated the new PINS-TOOL-IMX (v8) focused on the new DDR-Tool. We tested our LPDDR4 Memory interface sucessful but ther are some open questions.
1. Processor UART
There is no Option to select which UART is used? Default is uart1
There are 7 test which can performed. Test "Row hop read" and "Byte SSN memcpy" will allways fail.
We tested the two different boards with the DDR-Tool, and there is no problem.
3. vTSA (Data eye analysis)
There is an option to analyse all Byte Lanes and alle Bits but the test will nerver sucesful finish.If we analyse only on Byte Lane (8 Bits) there is noch problem.
4. Inport of *.ds File form RPA
We generated the *.ds File with the RPA Excel. During Import there is a notification "Note that some default settings will be applied to the component!"
Bute the user do not know, which Register is set or not.
It take us some hours to find out, that we must manual set the "Number of ranks in the DFI0 channel to 1.
Point 1,3 and 4 are only information to improve the tool.
Point 2: Have someone performed all stresstests sucessful or this a bug?
Thank you for your feedback! I have reported your findings to our Pins Tool experts in order to see if there is any workaround available.
Also, I just want to make sure. Which boards were used on your tests?
Please see below the response from our DDR Tool (for Pins Tool) development team:
I´ve also informed them that you realized the vTSA (Data eye analysis) in one of your TQ-Modules. May I ask which processor was used on it, and which Diags test were run?
thanks for your feedback.
We performed all possible tests with our new TQMa8MxML with a i.MX8 Nano Dual Lite:
- Walking One
- Walking Zeros
- Data is Address, Row hop read
- SSN memcpy x32
- Byte SSN memcpy x32
- Memcpy pseudo random data
- IRAM to DDR x32
- IRMA to DDR v2 x32
- Diag Write Margin
- Diag Read Margin
If you have a new Beta Version of the PINS-TOOL-IMX, we are able to test it.
Thank you for your patience. If you would like to test the latest version of the Tool, my suggestion is to contact your assigned FAE or DFAE in order to do so
My apologies for my delayed answer. I hope it helps!
