<Danct12> does anyone know why my sd card gave me i/o error and then retunes itself?
<Danct12> Jun 03 02:46:05 melt-pi5 kernel: I/O error, dev mmcblk1, sector 604890118 op 0x0:(READ) flags 0x80700 phys_seg 10 prio class 2
<Danct12> Jun 03 02:46:04 melt-pi5 kernel: dwmmc_rockchip fe2c0000.mmc: Successfully tuned phase to 135
<Danct12> Jun 03 02:46:04 melt-pi5 kernel: mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0)

<Danct12> it only does this when i load large files
<Danct12> this is a class a2 v30 card from samsung
<qschulz> Danct12: which board?
<Danct12> qschulz: orange pi 5
<qschulz> which kernel?
<qschulz> (I don't know why it's happening but this seems like important information to give :) )
<Danct12> v1.2 i believe (bought it when it's first available), and kernel is 6.1-rkr5 from https://github.com/armbian/linux-rockchip

<robmur01> most likely the signal quality/power/etc. is marginal for SDR104 speeds, so a long series of transfers just increases the likelihood of seeing an error
<robmur01> you could try checking/fiddling pinctrl properties - certainly I remember for HS200 eMMC most boards tended to need the driver strength cranking up from default

<robmur01> or perhaps just try dialling down the "sd-uhs-sdr104" cap in DT to "sd-uhs-sdr50" or lesser
<robmur01> (especially given that our "SDR104" on Rockchip is still only really "SDR74" anyway...)

Jookia has joined #linux-rockchip
<Jookia> o/ is it possible to use u-boot with no/minimal blobs to boot an rk3328?
warpme has joined #linux-rockchip
<CounterPillow> Jookia: yes
<CounterPillow> both dram training and tf-a are open and mainline
<Jookia> I have an RK3328 board that has decided it no longer wants to boot past ATF so I'm going to be doing a bit of bootloader debugging :(
<CounterPillow> check whether the ATF you use is one with broken FDT size limits, there was a version like that once where the FDT u-boot spl passed to ATF iirc couldn't be >64k
<Jookia> this happened between boots, so it's possibly a board issue
<Jookia> so this is mostly for troubleshooting what's wrong
franoosh has quit [Remote host closed the connection]
<Jookia> I did search online to try and find anyone else with similar symptoms (the board stops after INFO: SPSR = 0x3c9 in the boot log)
<Jookia> Is miniloader and TF-A is loaded in to RAM, not SRAM?
