Greetings!
I’m having an issue with a physical xtrx 1.2 device.
I’m wondering if this could be either the device doesn’t have any configuration on it, or perhaps EEPROM / Flash corruption?
-
The PCIe board and software work fine with a different
xtrx 1.2device. -
My understanding is that this device has never been flashed or even powered on prior to this issue being visible.
-
I’m using commit
368efb0154a459e42317ae270bf9716e776b82acof LimeSuiteNG to build the kernel module and the relevantlime*CLI tools. -
The device does show up ( with the serial number
00-00-00-00-00-00-00-00) usinglspci. -
Running
limeDeviceresults inLimePCIe: Failed to open (/dev/limepcie0/control0), errno(5) Input/output error. -
Doing a
modprobe limepcie, and subsequentrmmod limepcieresults in the followingdmesg:

Kernel modules: limepcie
An earlier version of the LimeSuiteNG repository using litepcie kernel module seemed to have a similar non-functional response.
Is there something that anyone would recommend other than soldering to the JTAG port?
Thanks!
edit: forgot to mention, the kernel is forcing 32bit DMA ( comes out of this thread ), without it the device is not found at all.
