I have this same problem when booting also. Revision 302, prebuilt and prebuilt kernel (latest). Just thought I'd let you know. Drew -----Original Message----- From: gum...@li...

Subject: [Gumstix-users] Touchscreen Stops Working (new info) Steve, Well, now I know I wasn't going crazy :) Just walked into my office this morning and booted the gumstix that had been off all night. Watched the console screen while sipping coffee and... ==== Starting i2c... tsc2003 i2c touch screen controller i2c: error: timeout i2c: msg_num: 1 msg_idx: 0 msg_ptr: 0 i2c: ICR: 000007e9 ISR: 00000004 i2c: log: tsc2003_i2c_detect: probing address 0x48 i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c_adapter i2c-0: i2c_pxa: timeout waiting for bus free i2c: error: exhausted retries i2c: msg_num: 1 msg_idx: 0 msg_ptr: 0 i2c: ICR: 000007e9 ISR: 00000004 i2c: log: I2C: i2c-0: PXA I2C adapter tsc2003 i2c touch screen controller tsc2003_i2c_detect: probing address 0x48 i2c: error: timeout i2c: msg_num: 1 msg_idx: 0 msg_ptr: 1 i2c: ICR: 000017ee ISR: 00000005 i2c: log: [00000045:000017e8] [00000085:000017ee] I2C: i2c-1: PXA I2C adapter i2c /dev entries driver === With no changes other than a reboot the touchscreen works! Perhaps the problem is in the i2c bus initialization? I have tried rebooting several times, but the touchscreen comes up every time at the moment. I will turn it off all day while I am at work and see if it will fail again this evening. -- Keith ------------------------------------------------------------------------ - Check out the new SourceForge.net Marketplace.
