Abhishekmishra2808 opened a new issue, #19120:
URL: https://github.com/apache/nuttx/issues/19120
### Description / Steps to reproduce the issue
### Steps to reproduce
1. Clone nuttx + nuttx-apps
2. Configure:
```bash
./tools/configure.sh esp32c3-devkit:usbconsole
Enable: `CONFIG_ELF`, `CONFIG_MODULES`, `CONFIG_FS_ROMFS`,
`CONFIG_BOARDCTL_ROMDISK`, `CONFIG_EXAMPLES_ELF`, `CONFIG_EXAMPLES_ELF_ROMFS`,
`CONFIG_EXECFUNCS_HAVE_SYMTAB`, `CONFIG_EXECFUNCS_SYSTEM_SYMTAB`,
`CONFIG_NSH_FILE_APPS`
3. Build and flash:
- make CROSSDEV=riscv32-esp-elf-
- make CROSSDEV=riscv32-esp-elf- flash ESPTOOL_PORT=/dev/ttyACM0
ESPTOOL_BINDIR=./
4. On NSH: elf
###Expected
ELF test binaries from ROMFS should run.
### Actual
riscv_exception: EXCEPTION: Instruction access fault
MCAUSE: 00000001, EPC: 3fc8b5d8, MTVAL: 3fc8b5d8
EPC is in DRAM (0x3fc8xxxx), which is not executable on ESP32-C3.

/>
### Notes
- libs/libc/elf/elf_load.c uses `lib_memalign()` (DRAM) when
`CONFIG_ARCH_USE_TEXT_HEAP` is not set.
- Current arch/risc-v/src/esp32c3/ has no `up_textheap_memalign()`.
- Legacy port has arch/risc-v/src/esp32c3-legacy/esp32c3_textheap.c
(instruction-bus alias).
- Requesting guidance whether text-heap support should be ported for ELF on
current ESP32-C3.
