libtimescale_core.a for ESP32

[houxn22]

Hi Paul,
I'm using ESP32 as host controller, and it's architecture is Xtensa LX6.
I have realized that there is a library named libtimescale_core.a_xtensa at src folder, and form #1 I already knew that the library is compiled for ESP8266.
ESP8266’s architecture is Xtensa L106, slightly different form Xtensa LX6. I have tested the libtimescale_core.a_xtensa library using the code below:

//////////////
#include <stdio.h>
#include "esp_system.h"
#include "timescale.h"
void app_main(void)
{
printf("SDK version:%s\n", esp_get_idf_version());
double x0[3] = {0}, q[3] = {128e6 * 512 * 3e-20, 128e6 * 512 * 3e-20 * 0.1, 128e6 * 512 * 3e-20 * 0.01}, T = 1e-6l * 0x100000;
timescale_instance_t * inst = timescale_init(NULL, x0, q, T);
printf("inst=%lu\n", (unsigned long)inst);
}
///////////
The ESP8266's result: inst=1074814716, and it seems all OK.
The ESP32's result: inst=0. And when I compile my app , there is some warnings like below:
"libtimescale_core.a(timescale.c.obj): warning: incompatible Xtensa configuration (ABI does not match)"
It seems that the library is not compatible with ESP32's architecture.

Then, can you please provide the libtimescale_core.a for ESP32 ?
The ESP32's SDK is not under the mynewt framework.
For the toolchain, please refer this link https://docs.espressif.com/projects/esp-idf/en/latest/get-started/linux-setup.html

Than you very much!

We had the same problem.
Timescale_xtensa is compiled using ABI=CALL0 only for ESP8266.
Can you help me to recomplie Timescale_xtensa use ABI=WINDOWED for ESP32 ?

Thank you very much!

Hi~
Would you please compile a version for Xtensa LX6 and Xtensa LX7?
That will be huge help for us!
Thask alot!
