Linux reboot issues with fman microcode

vinothkumars — Sat, 11 May 2019 11:21:25 GMT

Dear NXP,

I am working Yacto on T4160RDB-64B machine.

I flashed the fman micro code ( fsl_fman_ucode_t4240_r2.0_106_4_18.bin,

fsl_fman_ucode_t4240_r2.0_108_4_9.bin ) binary for Ethernet from the following link,

GitHub - NXP/qoriq-fm-ucode

When I issue the reboot command from Linux console,

with flashing the fman microcode

u-boot hang

But, without flashing the fman microcode

The u-boot boot without hanging.

Please provide the fix,

Regards,

VinothS

Use the fsl_fman_ucode_t4240_r2.0_106_4_18.bin microcode. See the Section 4.4.19.4 of NXP SDK 2.0-1703 documentation:

https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

Attached file contains this microcode.

See the Section 4.4.19.8.

The Table 105 contains NOR Flash memory map.

Have a great day,
TIC

Thank you for the reply. This the problem with hardware. Reboot works after implementing the RESET_REQ_B in Hardware side.

Thanks,

VinothS.
