Re: [uClinux-dev] uCLinux RAM usage
Yes, I do have a jffs2 on flash (about 5 Mbytes) and a ramdisk of 4 Mbytes ( ext2, with config_expand_nozeroes ). The ramdisk is empty.

[uClinux-dev] Kernel Stack ?
Hi, I am porting cypress EZ-Host usb driver for uclinux 2.4.32/coldfire. The system crashes ( without any messages) after module_init. there is one function call in my driver that seems to be responsible of this: toto(&int_data,0,0,0); if I replace this by toto(0,0,0,0), it does not crash anymore, even if the toto() only contains a 'return'. The 'crash' occurs only at the end of the module init ( my function toto is in the middle of the init and I can see other traces after the toto call). Could it be a kernel stack problem ? If so how could I increase this stack ? Thanks.

[uClinux-dev] traces in a driver
Hi, I would like to make some traces in a driver. I can't use printk because it introduces delay and affects the driver behaviour. Is there an easy way to log some traces in a file ?
