eLua on lpc1769

[agostain]

Hi ,

did somebody port elua to the lpc1769 board? Some hints on how to do it?  

I would really appreciate any help.

thanks,

Agostino

Not that I'm know. But should be fairly simple to do, since we already have a lpc1768 port.

Correct.  The port should be dead simple, basically making
modifications for clocking and perhaps other minor differences between
the 1768 & 1769.  If I understand correctly from some other pages the
only difference may be that it's clocked at 120 MHz rather than 100
MHz

So, it may be that even the current MBED sources will run (so long as
you ignore the pio module and turn off semifs in platform_conf.h
(under src/platform/lpc17xx)).

The following file might be relevant as well:
platform/lpc17xx/system_LPC17xx.c

thank you .. I'll give it a shot

Hi ,

I was able to flash the lpc1769 finally .

how do I get the elua prompt.... Is there a default UART used by elua?

I get no eLua prompt when connected to UART0 which is the default UART.

When porting to lpc1769 I followed the suggestions previously posted. Everything compiled. I commented out the mbed Pio module and use the lpc17xx one.

What am I doing wrong ?

thanks in advance

Hi,

The UART ID is declared in platform_conf.h. Look for the CON_UART_ID definition.

Best,
Bogdan

Hi,

I got that and it is 0


I am able to connect to the UART0 with a terminal but I don't get any lua prompt(after resetting the board ).

I disabled the mbed_pio module in order to use the platform specific pio functions...(in platform_conf.h)


// The name of the platform specific libs table
#define PS_LIB_TABLE_NAME   "mbed"

#define LUA_PLATFORM_LIBS_ROM\
  _ROM( AUXLIB_PIO, luaopen_pio, pio_map )\
  _ROM( AUXLIB_UART, luaopen_uart, uart_map )\
  _ROM( AUXLIB_PD, luaopen_pd, pd_map )\
  _ROM( AUXLIB_TMR, luaopen_tmr, tmr_map )\
  ADCLINE\
  _ROM( AUXLIB_TERM, luaopen_term, term_map )\
  _ROM( AUXLIB_PACK, luaopen_pack, pack_map )\
  _ROM( AUXLIB_BIT, luaopen_bit, bit_map )\
  _ROM( AUXLIB_CPU, luaopen_cpu, cpu_map )\
  _ROM( AUXLIB_PWM, luaopen_pwm, pwm_map )\
  _ROM( LUA_MATHLIBNAME, luaopen_math, math_map )\
  _ROM( AUXLIB_ELUA, luaopen_elua, elua_map )
 /* _ROM( PS_LIB_TABLE_NAME, luaopen_platform, platform_map )*/ <------- commented this

I'm sorry, I don't know what to tell you. It might be that simply
compiling the code is not enough, you also need some code changes for
LPC1769. This isn't easy to debug, I'm afraid.

Best,
Bogdan

I don't have a way to debug with jtag so I use the uart port to debug ...

in the /src/main.c

I succesfully initialize the platform with platform_init()

// Initialize platform first
  if( platform_init() != PLATFORM_OK )
  {
    // This should never happen
    while( 1 ) ;
  }

 while(1) platform_uart_send(0,0x55); <---- I am able to write to the uart

this is not the case after executing dm_init() and dm_register consequently...


// Initialize device manager
  dm_init();
 
  while(1) platform_uart_send(0,0x55);
 
  // Register the ROM filesystem
  dm_register( romfs_init() );

  // Register the MMC filesystem
  dm_register( mmcfs_init() );

....


What could be the problem of this? Hope somebody can help me with that ...

cheers,

Agostino

[agostain]

Ok it were compiler issues ... elua runs on the lpc1769 with the suggestions given on top ...

thanks for your support
