Re: [OpenWrt-Devel] Freescale P1020 WLAN support?
Bit of follow up for this issue. By tracking down the function that caused the crash, it was in 'crashlog_init_fs'. This function uses and 'address' that seem to be initialized if the config symbol: CONFIG_NO_BOOTMEM is NOT defined... Apparently it is defined, and the crashlog_addr variable apparently is used with an initialization of 0... By deselecting 'crash log' kernel config option, that allowed the kernel to boot to a command line prompt. John Clark.

Hi, is there currently anybody working on OpenWRT P1020-WLAN (Freescale) support? It is because we at the FeM e.V. are working on it trying to port the freescale patches forward and would like to join forces with anybody already working on it. Regards, M.

Re: [OpenWrt-Devel] Freescale P1020 WLAN support
Hello, I have once got p1020 running with openwrt. It should basically work without any specific target patches. I had to only adapt image building script. I will give it a try with 3.3 kernel and let you know. Wojtek PS At the moment I am fighting with p1010 as I get some spurious interrupts on second pcie slot. Maybe somebody has experienced similar problems? - Original Message - Hi, is there currently anybody working on OpenWRT P1020-WLAN (Freescale) support?

Re: [OpenWrt-Devel] Freescale P1020 WLAN support
I have just tried kernel 3.3 on p1020wlan and it seems to run with empty target patches folder. Only eth0 is working at the moment and most probably dts file has to be adapted slightly for eth1. What kind of other Freescale patches are you planning to port? Wojtek - Original Message - Hello, I have once got p1020 running with openwrt.
