SPI-EEPROM loses FPGA-content?

Post by dk5ras »

Hi,

I am using the 115k bladeRF, and maybe once or twice per week the SPI EEPROM seems to lose the FPGA file. I can load the FPGA temporarily, but autoload is gone. When using bladeRF-cli with -L to flash it again, this runs through without errors, and afterwards I can use it with autoload. For a while :) Wouldn't be less an issue if this procedure wouldn't take ages every time :-)

Just as follow-up, these problems seem to have gone with the later versions...

Hi Ralph,

Thanks for posting back. I meant to touch base with you on this -- this was resolved as part of an FPGA fix in v0.0.1, which was part of the dev-uart_speedup branch merge that took place recently.

If I remember correctly, there was some pin contention issue(s). Brian probably provide more details on this if desired -- I haven't been in the HDL yet really.

Cheers,
Jon
