This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for
esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled:
- LDFLAGS+=--enable-non-contiguous-regions
- ldgen.py replaces "arrays[*]" from sections.ld.in with objects under
SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo))
- "mapping[*]" - refers to all other data
If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at
least one block of code like this (otherwise it does not make sense):
.dram0.bss (NOLOAD) :
{
arrays[dram0_bss]
mapping[dram0_bss]
} > sram_low
.dram1.bss (NOLOAD) :
{
/* do not place here arrays[dram0_bss] because it may be splited
* between segments */
mapping[dram0_bss]
} > sram_high
When using a Linux system configured with `zh_CN.UTF-8` as `$LANG`,
and running raw cmake command to build the project (rather than using
`idf.py build`), output of objdump will be Chinese
(like `在归档文件 libesp_pm.a 中`), resulting in parsing error
`pyparsing.ParseException: Expected "In archive" (at char 0), (line:1, col:1)`
at entity.py line 129.
This commit forces objdump to use raw locale setting (`C`), to ensure
it always make English output that's able to be parsed.
Closes https://github.com/espressif/esp-idf/pull/7903
Previously ldgen determines the output file name on its own. This commit
makes it so that user can dictate what the output file name will be
for the processed template, if the user needs it for something else.
