[flashrom] Unable to update the bios

[Raghuramchary Jallipalli]

Hello Experts,
I have compiled the latest flashrom 0-9.5 source and tried to update the bios in the flash on our board, but I see the board gets hanged after executing the flashrom commands. But I don't see these errors in the reference board.

Please see below logs:

In the internal.c file I have negated the force_laptop variable in the if() condition,also commented the dmi_init(), compiled and used the command flashrom to program the bios.

Can you please let me know if this is a hardware issue or the flashrom utility issue.

Thanks for the help,
Raghu
