BL51E CAN is not working

[KonradJPE]

For HW rev. 01.01.00 CAN is not working.

Problem number is: MAIN_PR004890

[dpfeuffer]

MAIN_PR004890 "02F026L_pcie_boards_not_working_and_weird_behavior" describes:

OS: Linux, VxWorks

IP cores on G215 card not working:
- CAN
- UART
tested only under Linux: WIFI card on G-carrier also not working

F215 card OK.

something IRQ-related?

BIOS 1.05

weird things seen:
- PXE Boot in UEFI mode very slow (loading the very first files)
- PXE Boot in legacy mode Ubuntu 16.04.3 live the interface that was active during PXE cannot function in Linux later.
- USB Boot UEFI/legacy all interfaces are OK
- PXE Boot in UEFI mode all interface are OK

This issue was assigned to 13MD05-90_02_02. Is it solved?

[KonradJPE]

This issue is hardware issue - for BL51E. Some time ago Florian wrote about it. As I remember correctly UART (Rear interface) has also hardware bug.

Thanks for input, I found this e-mail from 2019-12-06:

Dear Konrad,

With this HW Revision it is not possible so the Problem number is: MAIN_PR004890 is still vaild.
The next HW Revision or model with F1 stepping in Apollo Lake doesn´t have this error anymore.

Best Regards
Florian Rauh

I will clarify it with Florian.

We will send you a new 09BL51E10 (F1 Stepping). Please repeat the CAN testing with the new HW.

We will send you a new 09BL51E10 (F1 Stepping). Please repeat the CAN testing with the new HW.

CAN works with the new hardware.
