An error about 'ucode' #6

Closed zxy110 closed 5 years ago

zxy110 commented 6 years ago

Hello, I've met linking problems when I run make install-firmware, which said

/home/zxy/nexmon/buildtools/gcc-arm-none-eabi-5_4-2016q2-linux-x86/bin/arm-none-eabi-ld: gen/patch.elf section '.text.ucode' will not fit in region 'ucode' /home/zxy/nexmon/buildtools/gcc-arm-none-eabi-5_4-2016q2-linux-x86/bin/arm-none-eabi-ld: region 'ucode' overflowed by 771 bytes

I haven't find where the ucode is set. The cmd content is

/home/zxy/nexmon/patches/bcm4339/6_37_34_43/mobisys2018_nexmon_channel_state_information_extractor# make install-firmware

HI,

I've solved this problem, I just go to the gen/memory.ld and change the value of ucode form 0x00006ec4 to 0x00007ec4
