I am designing a downloader hardware ,which is to burn a group of FPGA modules.
the FPGA module is a with a FPGA chip, and a BPI flash, the .bit file will be downloaded into the flash for self-boot up(BPI bootload).
For the single module, I download the hardware into FPGA through JTAG cable first, and then burn the flash;and I wonder how can I do with a group of module at one time. someone can give the advise, for the downloader hardware.

The daisy chaining is only the method for programming group of devices.
The other way is you can program flash devices separately at a time before assembling in module itself.

But the daisy chain is not the programmer I want to design.
And the downloader is a mold for pre-programming modules, so that they can be easily welded on the application PCB boards and do not need being programmed again.
My modules are designed as 2x5 PCB array, which are all same. I want to programm the 10 modules at same time,so I do not have to operate too many times for many modules batch process,such as 100 or 200.
