[U-Boot] Watchdog DM - ENOMEM(out of memory) error

[U-Boot] Watchdog DM - ENOMEM(out of memory) error

[Suniel Mahesh]

Hi,

I am trying to convert watchdog driver(omap3_wdt) on TI AM33XX platform to Driver Model.

I am getting the following error:


U-Boot 2019.07-rc4-00179-g77f6e2d-dirty (Jun 27 2019 - 15:11:15 +0530)

CPU  : AM335X-GP rev 2.1
Model: TI AM335x BeagleBone Black
DRAM:  512 MiB
WDT:   Started with servicing (60s timeout)
Error binding driver 'omap_timer': -12
Error binding driver 'omap_timer': -12
Error binding driver 'omap_timer': -12
Error binding driver 'omap_timer': -12

The watchdog DM driver has successfully got binded (checked the debug log).

The error is related to ENOMEM(out of memory). After a bit of search on the mailing lists I found 
out that may be tweaking CONFIG_SYS_MALLOC_F_LEN might resolve the error.

CONFIG_SYS_MALLOC_F_LEN is defined as 0x1000 initially, I changed it to 0x2000, 0x40000 and 0x8000
but the result stays the same..

Any pointers on what could be the issue ?

Hi,

The error is after the trace "DRAM:  512 MiB" , so after relocation!.

And in this case the CONFIG_SYS_MALLOC_LEN is used.

FYI: CONFIG_SYS_MALLOC_F_LEN  is used before relocation (tag '_F_ ')

Regards

Patrick

Hi Patrick,

thanks for the pointer and I understood your point. 

CONFIG_SYS_MALLOC_LEN is defined as SZ_32M which should be enough i guess ?

still trying to figure out what is causing that error.

This is very strange, particularly the fact that the error reports.

This patch should fix this error:
