Joel Bodenmann Posted May 5, 2014 Report Posted May 5, 2014 Hello iccp and welcome to the community,You say that the display is connected to Bank4 but out of my mind it looks like you try to initialize Bank0. This could lead to a hardfault and therefore freeze everything. I haven't taken a closer look to the reference manual but please check this to be sure. Back the days I've written this little guide leading you through the process of using FSMC with ChibiOS/RT. Probably that is of any help.The next thing I've noticed is that you actually touch the GDISPControl struct. This is a very bad thing to do. You're not supposed to ever come into contact with that struct and that's why it's nowhere documented nor listed in any examples. Please use the official API to change stuff like the orientation, backlight, contrast and so on to prevent anything bad from happening.I recommend you to use the demo you can find under /demos/modules/gdisp/basic until you get your display working.One more recommendation: Until you have a debugger, modify the hardfault routine of ChibiOS/RT in order to flash an LED for example very fast. This way you at least know whether it is stuck somewhere or something bad happened.~ Tectu
iccp Posted May 5, 2014 Author Report Posted May 5, 2014 Thanks for the fast reply.That guide was the first document I read. You're right, I'm using bank 1 (NOR/PSRAM), subbank 4 (NE4), I misspelled it.The freezing ocurred even before I tried to modify the GDISPControl struct, that was a desperate try out thinking that was some config missing. In fact, the main routine is based in the basic example...I'm going to try to modify the hardfault routine to display errors on the leds.The freezing could be caused by misconfigured timming? I've tried the one in the cortex-m4 example and the one described in an old post: http://forum.chibios.org/phpbb/viewtopic.php?f=11&t=725&sid=43ba3b809d2faef81c4924edfbd588be with the same results. The board in that old post is the same I've bought, but the config seems to be invalid.iccp
iccp Posted May 5, 2014 Author Report Posted May 5, 2014 I've added de hardfault routine to light a led, (I've forced a hard fault to test it works) and there's no hard fault on the code.iccp
iccp Posted May 5, 2014 Author Report Posted May 5, 2014 Still working on it. I've tryied to change some of the gfxconf; after that I get a half clear coloured screen, and a system freeze again, without a hardfault.gfxconf.h:#ifndef _GFXCONF_H#define _GFXCONF_H/* The operating system to use.

Joel Bodenmann Posted May 6, 2014 Report Posted May 6, 2014 Hello iccp,I'm sorry but I won't be able to take a closer look to this within the next 6 hours.Have you ever tried to lower the FSMC bus speed?~ Tectu
iccp Posted May 6, 2014 Author Report Posted May 6, 2014 Don't worry about time, I'm working on it on my spare time...Do you mean to set a bigger divider on ADD_SET, DATAST, BUSTURN? If you mean that, I've been playing around with this, even tried to set all 4 bits in all three vars with no luckThanksiccp
Joel Bodenmann Posted May 6, 2014 Report Posted May 6, 2014 Hello iccp,I'll have some time tonight and/or tomorrow afternoon to digg into the reference manual again. It has been quite some time since I last used the FSMC peripheral from scratch.You mentioned some external address decoder, did you make sure that you handle it properly?Also, have you ever run the official example provided by the board supplier to make sure that it's no hardware issue? I know, this is not very likely but just in case...~ Tectu
iccp Posted May 6, 2014 Author Report Posted May 6, 2014 Hello, Tectu.The official examples works fine on the board. I used it to be sure of the chipset, as this display can be provided with the SSD1289 or the ILI9320 chipset and is not marked on it.About the address decoder, I'm pretty sure the adrdess is correct. Is a 74LVC139, using as input NE4, and lines A23 and A24. The address needed for de LCD is the fourth one: A23 and A24 set (11).I tryied to change the address and in the other cases the LCD didn't response. I'll check it again against the example code.Thanks for your timeiccp

Abhishek Posted May 11, 2014 Report Posted May 11, 2014 Look in the reference manual for FSMC, you have the 4 BCRs in FSMC_Bank1->BTCR[0..3] followed by the 4 BTRs, they are not one after the other hence the index has to be 3 and 7 respectively for both cases.FSMC_BANK=6 is actually incorrect, we would have to use #define FSMC_BANK 3For the correct addressing of BTR4 here, replace: FSMC_Bank1->BTCR[FSMC_BANK+1] = FSMC_BTR1_ADDSET_2 | FSMC_BTR1_ADDSET_0 | FSMC_BTR1_DATAST_2 | FSMC_BTR1_DATAST_0; by 4Then to configure BCR4, so this line is left as is FSMC_Bank1->BTCR[FSMC_BANK] = FSMC_BCR1_MWID_0 | FSMC_BCR1_WREN | FSMC_BCR1_MBKEN;.That should lead to correct configuration of Bank 4, if all the switches in it are configured correctly.RegardsAbhishek
iccp Posted May 11, 2014 Author Report Posted May 11, 2014 Thanks for your response Abhishek.This was one of the first thoughts I had, but I think 6 is correct. For each subbank, you must define BTCR[n] and BTCR[n+1], so subbank 0, uses 0 and 1, subbank 1 uses 2 & 3, subbank 3 needs 4 & 5 and subbank 4 (which I'm using) should use 6 & 7.Anyway, I've tried it again and it freezes even before finishing initgfx();Thanks anyway for your time.iccp
