Dear all,
I'm trying to design a ZedBoard based application exploiting partial reconfiguration.
The system is FSBL based and runs a simple application which reads a full bitstream from SD, copy some partials into DDR and reconfigure a single partition as required.
Unfortunately, while I can read and successfully configure the PL reading the full bitstream from SD card, I seem to be unable to read any other file into DDR.
To do this, I used the "SD_TransferPartial" from the SW shipped with XUP1159 App Note.
Specifically, I do the following:
1) boot ("done" led on Zedboard is steady blue, PL is successfully configured)
2) initialization of the addresses where the partials are going to be placed
3) dump of these addresses. the initialization is successful
4) invocation of SD_TransferPartial. The function does _not_ return any error
5) dump of the addresses. They are still initialized with the original values
6) invocation of the operation on the (reconfigurable) core instantiated on the PL with parameters 8 and 5, read the result which is 13 (the core is a simple adder). Success
7) invocation of the partial reconfiguration (with a multiplier instead of an adder) reading the partial from the previous address. The function does _not_ return any error
8) invocation of the operation on the (reconfigurable) core instantiated on the PL with parameters 8 and 5, read the result which is 13 (the core is _still_ a simple adder). Fail (it should be 5*8=40)
So the problem is that the function is not placing any useful bit in the DDR. However, it opens successfully the file (I placed a xil_printf after the f_open function and it does work).
Do you know how to address this issue?
Best regards
Riccardo
