I don't have the circuit handy.Does the sdcard chip and processor chip have filter caps and stabilization caps (for current draw surge)? ------ Original message------From: Stephen CasnerDate: Wed, Oct 4, 2017 6:51 PMTo: OVMS Developers;Cc: Subject:Re: [Ovmsdev] OVMS v3 getting started On Mon, 25 Sep 2017, Mark Webb-Johnson wrote:
I’m having problems getting SD CARDs to work reliably. Some work recognise at all (a timeout error when mounting), and some will recognise but fail under heavy writes to the sd card. Frustrating as hell. I don’t think it is a hardware issue (even the googling that error message points to pull-up resistors as the culprit), but suspect some issue with the ESP IDF 2.1 library we are using. We’re working on this one at the moment. I would appreciate your feedback, when you get the boards, as to whether you get any success with SD CARDs.
I have a SanDisk Ultra 32GB micro SD card left over from playing with a Raspberry Pi. It is formatted FAT32 with name RECOVERY. When I insert it into the OVMS v3 and try the sd mount command, I get: OVMS > sd mount Error: SD CARD could not be mounted E (75093) sdmmc_cmd: sdmmc_card_init: send_scr returned 0x107 -- Steve _______________________________________________ OvmsDev mailing list OvmsDev@lists.teslaclub.hk http://lists.teslaclub.hk/mailman/listinfo/ovmsdev
