Error in flashing when the CC1200_CONF_MAX_PAYLOAD_LEN is large enough #24

Open nkaramolegos opened 5 years ago

nkaramolegos commented 5 years ago

Hello everyone, I am using the zolertia remote revb with the CC1200 rf module. When I have the following configuration on my project-conf.h:

I have the following error /usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: udp_test.elf section .bss' will not fit in regionFRSRAM'

On the other hand when I set CC1200_CONF_MAX_PAYLOAD_LEN to 1000 or 1023 it is ok. Any ideas? I think that the problem is not on the code but on flashing

Hi Nikos, I think that the RAM is overflowed with 1500. It's too huge for the system.

Best regards,

  • ...

    define CC1200_CONF_USE_GPIO2 1

  • define CC1200_CONF_802154G 1

  • define CC1200_CONF_MAX_PAYLOAD_LEN 1500

  • ... etc

I have the following error /usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: udp_test.elf section .bss' will not fit in region FRSRAM'

But in 802.15.4g the maximum payload size is 2047. How can I achieve it if the ram is not enough? Also, is there a way to decrease ram memory usage?

Hi Nikos, It' seems that this problem is completely firmware. We support only hardware issues and our drivers implementation. You can ask for the implementation of the 802.15.4 to contiki devel repo at: https://github.com/contiki-os/contiki/issues
