I am building btstack with msp430-gcc 4.7. I got the following error when
access a data in far.rodata region.
btstack/chipset-cc256x/bt_control_cc256x.c:194:(.any.text.bt_control_cc256x_next_cmd+0x16):
relocation truncated to fit: R_MSP430_16_BYTE against symbol
`cc256x_init_script' defined in .far.rodata.cc256x_init_script section in
objs/btstack/chipset-cc256x/bt_control_cc256x.o
the code looks like this:
#if defined(__GNUC__) && (__MSP430X__ > 0)
#define __data20 __attribute__((__far__))
#endif
const uint8_t cc256x_init_script[] __data20 = {............};
the access code is:
for(int i = 0; i < 3; i++)
hci_cmd_buffer[i]= cc256x_init_script[init_script_offset + i];
How can I work around this? This is a big project I don't want to switch to
huge memory model.
