[U-Boot] [PATCH 0/4 v4] arm: socfpga: Add Cadence QSPI support
by Stefan Roese 14 Jan '16

14 Jan '16

Hi! So this is my 4th posting regarding the Candence SPI driver on SoCFPGA. Again, SPI NOR flash is working. At least on SoCrates and on another custom SoCFPGA based board. The main change in this version is, that the Cadence driver now is a driver model (DM) based driver. And this needs the DT support which I posted just before. One of the reasons to enable DT support in SoCFPGA is, that I need to support multiple different SPI controllers for this platform. This is the QSPI Cadence controller and the Designware SPI master controller. Both are implemented in the SoCFPGA. And enabling both controllers is only possible by using the new driver model (DM). The DM SPI code only supports DT based probing. So it was easier to move SoCFPGA to DT than to add the (deprecated) platform-data based probing to the DM SPI suport. Note that I have patches to support the Designware SPI master controller also via DM in the queue. I'll post them shortly. Thanks, Stefan Cc: Chin Liang See <clsee(a)altera.com> Cc: Dinh Nguyen <dinguyen(a)altera.com> Cc: Vince Bridgers <vbridger(a)altera.com> Cc: Marek Vasut <marex(a)denx.de> Cc: Pavel Machek <pavel(a)denx.de> Cc: Simon Glass <sjg(a)chromium.org> Cc: Jagannadha Sutradharudu Teki <jagannadh.teki(a)gmail.com>

I've tried three different USB keyboards on an A20-Olinuxino-Micro and a Banana Pi, and I always get that error "cannot reset port N!?" where N is whichever USB socket I've plugged it into, and U-Boot cannot see the keyboard. Once Linux has loaded, the keyboard works without any trouble. Can anyone suggest what is causing this? Thank you, B.R. Oake.

[U-Boot] [RFC][PATCH 00/25] eeprom: Cleanup and support for multiple i2c busses
by Marek Vasut 10 Nov '15

10 Nov '15

This patch series first zaps a couple of ancient boards and ugly code which was in the way of proper cleanup for the eeprom command. Once that is done, the eeprom command undergoes proper cleaning. Finally, there is one patch which adds support for selecting on which bus the I2C EEPROM is. This functionality seems to be in high demand, which is exactly the reason why some boards decided to implement this themselves :-( This series makes U-Boot also less IoT, since it removes all the nice PHP, CSS and SQL stuff from it ;-) Marek Vasut (25): ppc: Zap ICU862 board ppc: Zap MHPC board ppc: Zap Hymod board ppc: Zap HWW1U1A board ppc: Zap IDS8247 board ppc: Zap TQM8260 board ppc: Zap TQM8272 board arm: Zap tricorder-eeprom eeprom: Shuffle code around eeprom: Zap CONFIG_SYS_I2C_MULTI_EEPROMS eeprom: Zap CONFIG_SYS_EEPROM_X40430 eeprom: Zap eeprom_probe() eeprom: Zap CONFIG_SPI_X eeprom: Pull out the I/O code eeprom: Pull out address computation eeprom: Make eeprom_write_enable() weak eeprom: Pull out CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS eeprom: Suck the ifdef into eeprom_init() eeprom: Pull out CONFIG_SYS_EEPROM_PAGE_WRITE_BITS eeprom: Pull out transfer length computation eeprom: Pull out the RW loop eeprom: Cultivate the ifdef mess eeprom: Add bus argument to eeprom_init() eeprom: Add support for selecting i2c bus eeprom: Clean up checkpatch issues README | 5 -

[U-Boot] Relocation issue - need help!
by Wolfgang Denk 21 Oct '15

21 Oct '15

Hi, I'm trying to track down a "syntax error" issue that gets triggered when erasing the U-Boot image in NOR flash. Symptoms look like this: => print update update=protect off 0xfc000000 +${filesize};erase 0xfc000000 +${filesize};cp.b 200000 0xfc000000 ${filesize};protect on 0xfc000000 +${filesize} => run update Un-Protected 2 sectors .. done Erased 2 sectors syntax error Protected 2 sectors => run update syntax error git bisect found commit 199adb6 "common/misc: sparse fixes" as culprit; breaking this down further showed a single line in common/cli_hush.c to trigger the problem. This patch fixes it: --- common/cli_hush.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/common/cli_hush.c b/common/cli_hush.c index 38da5a0..5bbcfe6 100644 --- a/common/cli_hush.c +++ b/common/cli_hush.c @@ -3127,7 +3127,7 @@ static void mapset(const unsigned char *set, int code) for (s=set; *s; s++) map[*s] = code; } -static void update_ifs_map(void) +void update_ifs_map(void) { /* char *ifs and char map[256] are both globals. */ ifs = (uchar *)getenv("IFS"); -- 1.8.3.1 But I still have bad feelings - symptoms indicate that this is actually a relocation issue, as it only gets triggered when erasing the U-Boot image in NOR flash, so probably there are still pointers to data in NOR being used. This patch here is not suited to fix the original cause of this issue. But then, I do not see where there might be a relocation problem. To be sure I even verified that "ifs" and "map[]" are really in RAM all the time. Has anybody an idea how to further track this down? Or is the patch above actually a real fix? If so, why?

Hi, We have recently started working on arndale and running u-boot head on it. Seems like it is crashing on our setup with a data abort on usb start.

[U-Boot] fatwrite problem
by Ruud Commandeur 12 Oct '15

12 Oct '15

Hi Everyone, Sinced a few days I noticed some problems writing the uimage to a FAT partition on my SD-card. At first I was afraid of some (physical) SD-card problems, but it appears to be related to he size of the uImage. With some further testing (and adding some debug printing), I could easily reproduce the problem: //4K file, result OK fatwrite mmc 0:1 42000000 testfile 1000 writing testfile set_cluster; clustnum: 5, startsect: 176, size 2048 set_cluster; clustnum: 6, startsect: 180, size 2048 set_cluster; clustnum: -6, startsect: 132, size 2048 4096 bytes written //512 bytes file, timeout error, file not written fatwrite mmc 0:1 42000000 testfile 200 writing testfile set_cluster; clustnum: 5, startsect: 176, size 0 MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! set_cluster; clustnum: 5, startsect: 176, size 512 MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! set_cluster; clustnum: -6, startsect: 132, size 2048 MMC0: Bus busy timeout! 512 bytes written It seems to be related to he problem reported here: http://www.mail-archive.com/u-boot@lists.denx.de/msg107212.html Once the size of the set_cluster call equals 0, the mmc command is incomplete and times out. In the earlier reported problem, a patch is mentioned, but not available for dowload here. Also in the latest versions of the git repository I could not find a patch for this problem. Can anyone tell me if there is a fix for this problem? Regards, Ruud
